(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An ac generator with a frequency of F=25 Hz and an rms voltage of 15 V is connected to a C=32 µF capacitor. Assume that the generator produces a sinusoidal waveform.

(a) What is the maximum current in the circuit? mA

(b) What is the current in the circuit when the voltage across the capacitor is 7.5 V and increasing?

(c) What is the current in the circuit when the voltage across the capacitor is 7.5 V and decreasing?

2. Relevant equations

Irms= Vrms*Xc

Irms= [1/(2)^(1/2)]* Imax

3. The attempt at a solution

part (a): already figured it out using Irms= Vrms*Xc and got the answer of106.629 mA, which is correct.

part (b) and (c): I tried using the Irms= Vrms*Xc equation and plugging in 7.5 Volts as V and solving for I, since I already have Xc which is just 1/(angular freq. * Capacitance)
