Write joule's law of heating??
Help

Answer 1

Hi,
Joule's law of heating

The heat produced by a conductor when current flows through it is-
1>directly proportionate to the square of the current flowing through it at given temperature.
2>directly proportionate to the resistance for a given current.
3>directly proportionate to the time for which the current flows in conductor...

FORMULA    H=I^2Rt

☣ What is Joule heating ☣

➡ The process by which the passage of an electric current through a conductor produces heat is called the Joule heating.

⭕ Joules law of heating

✴ The heat that is generated because of the current flow in an electric wire is described in Joules law .

✴ Joules first law

➡➡➡➡ Q = I^2  R T

EXPLANATION of Q = I^2 R T

♣ Q = amount of heat,

♣I = electric current

♣R = amount of electric resistance in conductor

♣T = time

✴ Points ✴

1. when the electrical resistance and current supply is constant.

2. when the current in the circuit and the flow of current is not changed.

3. when the resistance and current flow is kept constant.
