Question: A capacitor is connected across an ac source that has volt-age amplitude 60.0 V and frequency 80.0 Hz. (a) What is the phase angle

A capacitor is connected across an ac source that has volt-age amplitude 60.0 V and frequency 80.0 Hz. 

(a) What is the phase angle ϕ for the source voltage relative to the current? Does the source voltage lag or lead the current?

(b) What is the capacitance C of the capacitor if the current amplitude is 5.30 A?
