Question

derive an expression for joule law of heating
​

Answer 1

Answer:

    P  = VI  

P  = VI                     H = P × t = Vlt

P  = VI                     H = P × t = VltBut             V = IR (ohm's law) 

P  = VI                     H = P × t = VltBut             V = IR (ohm's law) ∴                H = I2Rt

Explanation:

Hope it will help you!.....

Answer 2

Answer:

hey babe,, here is your answer..

Explanation:

therefore, P = VI

H = P × t

= Vlt

But , V = IR (ohm's law)

∴ H = I^2Rt

hope it helps u frnd !
