Question

In a circuit, a wire of certain length and thickness was used and reading of ammeter was noted. Now it is
replaced by a thicker wire of same material and same length in same circuit. The reading of ammeter will
increase
decrease
remain same
may increase or decrease​

Answer 1

Answer:

The reading of ammeter will increase

Explanation:

Resistance is inversely proportional to the radius of the wire. So, thicker wire provides less resistance and the current passing through the cross-section of the wire will increase provided that the potential difference between the ends of the wire remains constant.
