An ac series circuit consists of a voltage source of frequency 60 Hz and voltage amplitude V, a 533- resistor, and a capacitor of capacitance 6.4-F.

What must be the source voltage amplitude V for the average electrical power consumed in the resistor to be 989 W? There is no inductance in the circuit.
