A capacitor is connected across an ac source that has voltage amplitude $51\mathrm{.}0$ V and frequency $78\mathrm{.}5$ Hz $.$

Part A

What is the phase angle $$ for the source voltage relative to the current? Express your answer in degrees.

Part B

Does the source voltage lag or lead the current?

lag

lead

Part C

What is the capacitance C of the capacitor if the current amplitude is $5\mathrm{.}00$ A $?$

Express your answer with the appropriate units.
