How To Work Out Capacitor Voltage

How To Work Out Capacitor Voltage. I = v/z where v is the voltage across the rlc circuit, i is the current through the series circuit and z is the rlc impedance. The voltage is switched on and off periodically over different intervals.

We can pull out the 500 from the integral. However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
