Question

a 5degree C rise in temperature is observed in a conductor by passing a current . When the current is doubled the rise in temperature will be approximately

1- 20degree C 2- 16 degreeC

3-10degree C 4- 12 degree C

Answer 1

HOLLA MATE!

HERE IS YOUR ANSWER—

We know that, heat is directly proportional to the current.

So, when current is doubled then heat is also doubled....

So, the temperature becomes

5 * 2 = 10• C
