The diagram below shows two coils A and B placed parallel to each other at a very small distance. Coil A is connected to an AC supply. G is a very sensitive galvanometer. When the key is closed

constant deflection will be observed in the galvanometer for 50 Hz supply

visible small variations willl be observed in the galvanometer for 50 Hz input

oscillations in the galvanometer may be observed when the input AC voltage has a frequency of 1 to 2 Hz

No variation will be observed in the galvanometer even when the input AC voltage is 1 or 2 Hz

Text Solution

Verified by Experts

The correct Answer is:

At low frequency of 1 to 2 Hz also, oscillations may be observed.
