Question

how work done is equal to heat produced in a conductor?​

Answer 1

They collide with atoms or ions of conductor and with each other.As a result of collision,kinetic energy of free electrons is transferred to atoms or ions. They then start vibrating with large amplitude. Thus total energy of ions increases. ... The work done is equal to heat produced in the conductor

Answer 2

Answer:

work done is equal to heat produced in a conductor

Explanation: Here

I=current

Q=charge

R=resistance

v=potential difference

t=time

Then,

    V=W/Q

     W=vQ--- (1)

But,

I=Q/t

therfore Q=It

From Ohm's Law

R=V/I

therefore V=IR

Now putting the value of V in eqn. (1) we get

W=IR x It

  =I^2Rt

but we have H=I^2RT

From this we can say that W=~H

this is for standard 10 so u will get little complicated ask me if there is any misunderstand
