Q. The condition for zero phase shift in wein bridge oscillator is achieved by

A
Connecting feedback to non-inverting input terminal of op-amp
B
Balancing the bridge
C
Applying parallel combination of RC to the feedback network
D
All of the mentioned
Solution:

In wein bridge oscillator, the feedback signal in the circuit is connected to the non-inverting input of op-amp. So, feedback network does not provide any feedback and the condition of zero phase shift around the circuit is achieved by balancing the bridge.
