In the given circuit, connect a nichrome wire of Length 'L' between points X and Y and note the ammeter reading.

State the changes that are observed in the ammeter reading if we double the area of cross- section without changing the length in the above experiment.

A

Ammeter reading will increase

B

Ammeter reading will decrease

C

Will decrease to half

D

No charge in ammeter reading

Text Solution

Verified by Experts

The correct Answer is:
B

The ammeter reading will increase (becomes two times). This is because as area increase, resistance decreases and hence current increases.
