A 100 microfarad capacitor in series with a 40 ohms resistance is connected to a 110V , 60 Hz supply (a) what is the maximum current in the circuit (b) what is the time lag between the current maximum and voltage maximum.

Given:

C = 100 μF = 100 × 10^{-6} F = 10^{-4} F

R = 40 Ω

E_{v} = 110 volt

E_{0} =

v = 60 Hz

ω = 2Πv = 120 Π rad/s

I_{0} = ?

In RC circuit, as

In RC circuit, voltage lags behind the current by phase angle Φ,

where
