Q1:

If an inductance L is connected in one arm of bridge and resistance R1, R2, R3 in other three arms

A the bridge cannot be balanced

B the bridge can be balanced

C the bridge is balanced for some specified value of frequency

D the bridge is balanced for some specific values of R1, R2, R3

ANS:A - the bridge cannot be balanced

To balance the bridge both magnitudes and phase angles of voltages have to be balanced.
