# RC circuit frequency

Not what you're looking for?

Hi. Can someone please walk me through how to do the following problem?

An RC circuit consists of a resistor R = 32 ohms, a capacitor C = 2.5 micro-F, and an ac generator with an rms voltage of 120 V. At what frequency will the rms current in this circuit be 2.9 A?

Thank you.

##### Solution Summary

This solution uses calculations for impedance and current to find frequency.

##### Solution Preview

Impedance offered by an RC circuit is given by,

Z = sqrt[R^2 + (1/wC)^2]

Where w = 2*pi*f

We know that, Current I = Voltage/resistance = V/R
