Question

state joules law of heating and mathematical form of this law​

Answer 1

work done by carring a charge Q through a p.d :v is given as

Q=IT

using ohm's law,V=IR

W=I^2RT

this work done is carring a charge through the wire appear as the heat produce i.e.

H=VIT

=I^2RT

this energy is decipited as heat

and this is called joule's law of heating.

hope its helps u plz mark me as brain list

Answer 2

Answer:

Explanation:

Hii friend,

Joyless law of hearing is about on hearing.

It is expressed as

H= I²Rt (or) V²/R×t

where (I=V/R).

In this, H= heat of the substance

I= current through the substance

R= resistance

T= temperature.

hope this helps you a little!!!
