Once the battery is full, the charging circuit stops drawing power from the charger until such a point where it decides to resume charging. Simpler 'chargers' deliver up to a certain amount of current at a fixed voltage depending on what resistance the charging circuit presents to the charger.
Therefore, answering the initial question, if we replace a car battery with a higher capacity one, we will be able to leave the elements that depend on the battery in operation for a longer time. In addition, with the same consumption the higher capacity battery will discharge less, which in the long run will result in a longer battery life.
If the current is above what battery is expected to provide, you can expect the battery to have lower voltage than expected, to overheat, maybe even explode. If the current provided by the battery is sufficient, the voltage drop isn't going to be as big.
When current is supplied by a battery, the battery's voltage usually drops. The drop depends on the type of battery and the current. If the current is above what battery is expected to provide, you can expect the battery to have lower voltage than expected, to overheat, maybe even explode.
Voltage: As the resistance of what we have connected to the battery is fixed, the higher voltage we have, the more current we can provide. Or put another way, the voltage will determine the current intensity and the higher the voltage, the more intensity we will give. - If a battery is discharged, it will give less intensity of current.
Batteries are normally rated in Ampere-hours (Ah), not in Amperes. An Ampere-hour is a measure of the energy stored in the battery, and is not directly related to the current that the battery can deliver. By adding a battery in parallel, you do not increase the current. You increase the maximum current that the motor can take.

$begingroup$ @AO practically every adapter is designed to run off mains (house power), and the nature of "switching power supplies" makes it easy for them to support a wide range of input voltages with little impact on performance. The damage is likely not immediate, the 18V is fed to the charge controller for the laptop motherboard, typically these will have capacitors and …
What would happen to a 40 Ah lead acid battery if the charging current is as low as 750 mA? Charging capability = Yes The LA battery will be charged at C/50 current rate: 0.75/40 ~ 1/50. If battery if fully discharged, it will reach full charge after 50 hours (2 full days).
The mobile batteries have a controller built-in that ensures the same input to the battery regardless of whether or not the charger''s current rating is greater than needed. You should choose a charger with a rating of the same voltage, not less nor higher, and a current rating of the same or high to ensure a cooling charging process.
Higher wattage does not damage the battery because the phone has mechanisms for controlling the amount of current that will enter the battery. Since wattage is a product of voltage and amperage, You should not use a higher voltage on your phone, but in the case of amperage, you are good as long as the output amperage is equal to or higher than …
for short, of the battery is 3. 0 V. Now here''s the question. A resistor with the same resistance as the lamp is added to make circuit two, that you can see on the right, I''d like you to predict and explain what will happen to the current through the ammeter, and what will happen to the current through the lamp.
In your battery example, there is no return current path so no current will flow. There is obviously a more deep physics reason for why this works but as the question asked for a simple answer I''ll skip the math, google Maxwell''s Equations and how they are used in the derivation of Kirchhoff''s voltage law. Batteries do make a good example for this simply …
$begingroup$ @KianJ. Because the motor is in series with the switch they must have the same current through them. Now, you can change that if you make the motor not in series with the switch, such as by using the switch to turn on a relay that turns on a motor - then the switch only needs to handle the current to turn on the relay, and the relay needs to handle …
Output current of a voltage source? Normally, the device will draw up to its rated current when supplied with its rated voltage. There exist constant-current sources that will adjust the voltage in order to deliver the rated current. If that output current from such a supply exceeds the rated input current of the device, it could cause damage.
If you supply higher voltage to the diode (if necessary, bypassing any regulator or current limiting resistor), the practical effect is to bump up many more of them (the actual voltage in the junction doesn''t drop off as quickly). So the laser will have a much greater intensity. (Your higher voltage supply must also have sufficient current ...
When the battery is connected and tries to draw more than the set current, the charger will drop its voltage to limit current. At the same time the battery voltage will rise due to the charging current. When battery voltage reaches 8.4V the charger will progressively lower the charging current to prevent the voltage from going higher than 8.4V.
Recently, I change my stock battery to a maintenance free battery. I heard that my ride (Lancer 2006)''s battery needs 55-60 Amp but I install a MF battery of 70 Amp. It was a direct fit in and replacement of my old stock battery. Are batteries are higher Amp bigger in size? Any side effect to the...
The basic algorithm for Li-Poly batteries is to charge at constant current (0.5 C to 1C) until the battery reaches 4.2 Vpc (volts per cell), and hold …
$begingroup$ @Dejvid_no1, sounds like you are presenting guess work instead of scientifical facts, or you are negligent in how you express yourself. First you say "no, [not] at all" — it''s never safe to fully discharge. …
$begingroup$ "My thought process is that the voltage difference will cause current to flow" - what voltage difference? If you connect one terminal of the battery to the Earth, there is no voltage difference between that terminal and Earth. Yes, there is a voltage difference between the other, unconnected terminal but, since it is unconnected, there is zero current in or out of this terminal.
As mentioned above, the simulator will answer the question with 99% certainly. That said, as a rule of thumb, assuming the battery can deliver the current, increasing the controller amps will not affect a higher top speed on the flat, but will increase acceleration and the achievable top speed on a hill. This is because the controller current limit (typically) only …
Answer : Option A) Increase. Explanation : When a bigger battery is installed there is an increase in amount of current observed. As per Ohm''s law; Voltage = Current X …
In this heavily upvoted answer the answerer states that it is okay to supply a component with more current than what it''s rated for. The analogy is that (paraphrasing here) "If Johnny wants to eat two apples, he''ll …
After you replace the battery in your laptop, the next step is to check the new battery. This inspection is important to make sure that the new battery works well and will last for a long time. How to Check New Laptop Battery. Here are some things to look for when checking your new laptop battery: 1. Check the new battery''s voltage. A laptop ...
However, the number of electrons inside of a battery doesn''t change in normal operation no matter what. Applying Kirchhoff''s current law, you can check it for yourselves. No …
So, if you are powering a load with a battery that is also being charged then it will effectively cancel the currents out. So if you are powering a load with 3A and charging the battery at 2A, then you''ll be effectively discharging the battery at 1A. So it will take longer to discharge the battery since you''re only taking 1A out. But it ...
A higher mAh battery may not charge correctly if the charging circuit cannot handle the increased power needs. This incompatibility can lead to slower charging times or, in worse cases, battery damage. A report from the IEEE (Institute of Electrical and Electronics Engineers) in 2020 highlights the importance of matching battery and charging specifications …
With both options available, the answer is a qualified yes, you can replace the original with a larger capacity, but there''s an IF: that''s possible only if your system doesn''t …
Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I''m also assuming a constant charging voltage from an alternator.
How will increasing the voltage of a battery affect the strength of an electromagnet? How can you make an electromagnet stronger? What happens when a wire is wound into a coil around an …
I''ve just bought a portable battery, but the portable battery don''t comes with an adapter for the house current; it only comes with a USB cable so I can charge it with my laptop. My mobile phone came with a charger, and I want to know if is safe to use that charger with the battery without problems, even though the output has a higher amperage ...
You cant squeeze a larger battery in to the same physical space (and if you could you would not want a higher voltage battery - higher (milli)amp hours@ 7.7 volt is what is required.) 2.5 hours is very low for that laptop (manufactuers talk about 11 hours) - unless you are doing heavy gaming it should last longer then 2.5 hours. This likely ...
