We see that every hour, a 3,000W device uses 3 kWh of electric energy. Running it for a whole month will burn 2,160 kWh of electricity. Let''s calculate the cost of that: Electricity Cost = 2160 kWh * $0.1319/kWh = $284,90. As we can see, running it 24 hours per day will end up in a $284,90 increase in our monthly electricity bill.
Example 1: A capacitor on a computer motherboard is known to have capacitance of 5 Farads and the voltage is known to be 50 mV. What is the capacitor's charge in Farads? Since a 1 Coulomb = 1 Farad-Volt we first convert 50 mV to 0.050 V and then apply the capacitor charge equation C = Q · V = 5 · 0.050 = 0.25 C.
You can easily find the energy stored in a capacitor with the following equation: where: E E is the stored energy in joules. V V is the potential difference between the capacitor plates in volts. Replace each parameter, and the result will be the energy the capacitor can hold.
A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.
Let’s use the electricity usage calculator above: We see that every hour, a 3,000W device uses 3 kWh of electric energy. Running it for a whole month will burn 2,160 kWh of electricity. Let’s calculate the cost of that:
Another output of the capacitor energy calculator is the capacitor's charge Q Q. We can find the charge stored within the capacitor with this expression: where again: Q Q is the charge within the capacitor, expressed in coulombs. The capacitor energy calculator finds how much energy and charge stores a capacitor of a given capacitance and voltage.
