A signal voltage V(t) = V0 sin ωt is applied across an ideal capacitor ‘C’
A. current I (t) is in phase with voltage V (t)
B. current I (t) is leads with voltage V (t) by 180°
C. current I (t) is lags with voltage V (t) by 180°
D. over a fully cycle, the capacitor does not consume any energy from the voltage source.
Answer:D
A signal voltage V(t) = V0 sin ωt is applied across an ideal capacitor ‘C’
A. current I (t) is in phase with voltage V (t) B. current I (t) is leads with voltage V (t) by 180° C. current I (t) is lags with voltage V (t) by 180° D. over a fully cycle, the capacitor does not consume any energy from the voltage source.
