Question

It's urgent please give me answer in details
Thick wire and thin wire made from same material and of same length are connected one by one to the same source. In which case a larger current will flow in the circuit? Justify your answer.

Answer 1

Answer:

thick wire

Explanation:

because the resistence is directly proportional to area of its cross section

Answer 2

The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. This is due to the fact that the resistance of a wire is inversly proportional to the square of its diameter. A thick wire has a greater diameter and hence lesser resistance making the current to flow through it more easily. On the other hand, a thin wire has smaller diameter and hence greater resistance to the flow of current through it.
