Question

4a current is passing through a current carrying conductor having resistance 400 at a time 10 minutes calculate the amount of heat produced?​

Answer 1

Answer:-

• Current =I=4A
• Resistance=R=400ohm
• Time =t=10m=600s

We know that

• According to Joules law.

$\boxed{\sf Heat=I^2Rt}$

$\\ \rm\longmapsto Heat=4^2\times 400\times 600$

$\\ \rm\longmapsto Heat=16\times 240000$

$\\ \rm\longmapsto Heat=3840000J$

$\\ \rm\longmapsto Heat=3.8\times 10^6J$

$\\ \rm\longmapsto Heat=3.8\times 10^3KJ$
