SUMMARY
The discussion focuses on calculating the peak voltage across a 4.0 μF capacitor in an AC circuit. The user successfully determined the peak current supplied by the emf to be 25 mA. To find the peak voltage across the capacitor, the relevant equation is V = I * XC, where XC is the capacitive reactance calculated using the formula XC = 1/(2πfC). The user is encouraged to explore the concept of a capacitive voltage divider for further understanding.
