Question

In a series L-C-R circuit, resistance R = 10 ohm and impedance Z = 10 ohm. The phase difference between the current and the voltage is
a) 0°
b) 30°
c) 45°
d) 60°

Answer 1

"The question has the following values.

R = 10 ohms

Z = 10 ohms

Since it is a series L-C-R circuit and the current and voltage are in the same phase as the circuit contains only resistance phase difference will be (a) Zero.

In case of resistance, the angle between current and voltage is zero.

"

Answer 2

Phase Difference is zero because in series LCR circuit current and voltage are in same phase so that there is only resistance , angle between voltage and current is zero.
