RL Circuits

Q1:
If the resistance is larger than the inductive reactance in the given circuit, the phase angle is _______.

A less than 0°

B between 0° and 45°

C between 45° and 0°

D greater than 90°

ANS:B - between 0° and 45°

Let us assume resistance is infinity than tan-(xl/infinity) that is tan-(0) so it is zero. and in second case assume r=xl than tan-(1) that is 45 degree.

So answer is 0degree and 45degree
