    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.

    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

    Now, ...

    Solution Summary

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