RL Circuits

Q1:
Which of the following statements is true if R = 100 omega.gif and XL = 100 omega.gif in the circuit in the given circuit?

A Each component drops 5 V.

B The impedance equals 200 omega.gif.

C The power factor equals 1.

D The phase angle equals 45°.

ANS:D - The phase angle equals 45°.

theta=tan-(xl/r) that is tan-(100/100) i.e is phase angle is equal to 45degree
