Question

a good amount of heat is produced in the nichrome wire for the same current as compared of that of copper wire. justify the statement. state the law of which explains the above observation.​

Answer 1

Answer:

Nichrome wire is more resistant material than copper. Higher the resistance, more is the heat. This is called the heating effect due to electrical current.

H = I$R^{2}$T   (I- CURRENT ; R - RESISTANCE ; T-TIME)

Answer 2

Explanation:

nichrome wire is more resistant material than copper .Higher than the resistance more is the heat. This is called the heating effect due to electrical current
