RL Circuits - Technical MCQs

Q1:

Which of the following statements is true about a lag network?

A An increase in frequency causes an increase in phase lag.

B An increase in frequency causes an increase in the magnitude of the output voltage.

C A decrease in frequency causes an increase in phase lag.

D A decrease in frequency causes a decrease in the magnitude of the output voltage.

ANS:A - An increase in frequency causes an increase in phase lag.

Thetha = inverse tan(2*pi*f*L/R).

So, if f increases phase lag increases.
