With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
A simple circuit is shown shows four capacitors and resistors in parallel. On the left hand side of the circuit an LED is seen, this is protected by a 300 ohm resistor. As the switch is closed the capacitors can be seen to charge up and the LED lights immediately.
Discharging a capacitor through a resistor proceeds in a similar fashion, as Figure illustrates. Initially, the current is I9 − V0 R I 9 − V 0 R, driven by the initial voltage V0 V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V V.

An electrolitic capacitor does have a + and a - connection. They are NOT called cathode and anode, as they do with diodes. The + connection goes to the point with the highest potential (VCC or +V)
Connect the multimeter leads to the capacitor terminals. Connect the positive (red) multimeter lead to the capacitor anode lead and the negative (black) lead to the capacitor cathode lead.
