Question

किसी चालक तार के सिरों पर विभवांतर 30 वोल्ट है तथा धारा का मान 3 एंपियर है| तार में ऊष्मा प्रवाह की दर की गणना कीजिए|

Answer 1

H=vi
=30*3
=90
rate of formation of heat = voltage*current

Answer 2

The heat produced in the circuit is 90 J.

Explanation:

Given that,

Voltage, V = 30 volt

Current in the circuit, I = 3 A

We need to find the heat produced in the circuit. Due to flow of electric current heat is produced in it. The heat produced is given by :

$H=V\times I\times t$

If t = 1 seconds

$H=30\ V\times 3\ A\\\\H=90\ J$

So, the heat produced in the circuit is 90 J. Hence, this is the required solution.
