(3marks question)

Answer 1

Answer:

P=power

t=time

P=electric energy÷t

p×t=electric energy

electric energy =p×t

H=IR×It

H=I2Rt

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!!!
