Question

Derive the expression for Joule's heating effect of current.. No Spam Ans !!!

Answer 1

H=I^2×R×T

W=VIT

W=H also

H=IR.IT

H=I^2RT

Answer 2

HELLO DOST

Here is the derived expression for Joule's heating effect of current.

We know that H = VIT

And V = IR by Ohm’s law

⇒ H = (IR)IT

⇒ H = I2RT

This is the Mathematical form of the Joule’s law of heating effect.

Iron and heater are the devices that use the Joule’s law of heating effect.

HOPE IT HELPS YOU DEAR FRIEND
