Question

7. Ritutook a wire of length 10 cm and Reenu took a wire of 5 cm of the same material
and thickness. Both of them connected the wires as shown in the circuit given in
Figure. The current flowing in both the circuits is the same.
(i) Will the heat produced in both the cases be equal? Explain.
(ii) Will the heat produced be the same if the wires taken by them are of equal lengths
but of different thickness? Explain.

Answer 1

Answer:

$h = {i}^{2} rt$

no heat will not remain same because heat is directly proportional to length

Answer 2

Explanation:

$h = {i}^{2} rt$

1. no heat will not remain same
2. heat is directly proportional to length
