What maximum current is delivered by an AC source with AVmax = 58.7 V and f = 72.1 Hz when connected across a 3.70-µF capacitor? Step 1 The applied AC source determines the voltage amplitude and frequency. We will compute the reactance of the capacitor at this frequency and use the definition of reactance to find the current. The impeding effect of capacitance C in an AC circuit with frequency f is called capacitive reactance. Capacitive reactance is defined by the following equation. 1 Xc = 2zfC For the maximum current I Imax Imax = = ΔV, = max Xc Substituting the expression for capacitive reactance and solving for the current gives ΔV. max Xc max = at applied voltage ΔV, AV max .
