AI Generated Solution

To solve the problem step by step, we will first calculate the capacitive reactance (Xc) and then find the RMS and peak currents in the circuit. Finally, we will analyze the effect of doubling the frequency on the capacitive reactance and current. ### Step 1: Given Data - Capacitance (C) = 15.0 µF = 15 × 10^(-6) F - Voltage (V_rms) = 220 V - Frequency (f) = 50 Hz ### Step 2: Calculate Capacitive Reactance (Xc) ...
