Question

Outline Joule’s equation of electrical heating and explain the terms in the equation.

Answer 1

Step-by-step explanation:

The Joule's law of heating states that the heat evolved in a conductor is directly proportional to the product of square of current and resistance. It is given by :

`H=I^2Rt`

I is current

R is resistance

t is time

Ohm's law, V = IR

So,

`H=(V^2t)/(R)`

V is voltage
