How to Calculate Joule Heating?

The simple steps to compute the heat produced by flowing current through a conductor are along the lines.

  • Find the electric resistance in a conductor, time, and electric current.
  • Sqaure the electric current and multiply it with the product of time and resistance.
  • The obtained value is called the joule heating.

Joule Heating Formula

Joule's law of heating is a description of the rate at which resistance in a circuit converts electric energy into heat energy.

Joule's first law represents the relationship between the heat caused by electric current flowing through a resistance.

The Joule heating formula is provided below:

Q = I²Rt


Q is the amount of heat

I is the electric current

t is the time

The amount of heat generated is proportional to the wire's electrical resistance when the current flow in the circuit and the current flow not changed, it is proportional to the square of the current flow through the circuit when the current supply and electrical resistance is constant and it is proportional to the time of flow.


Question: An heater of resistance 500 Ω is connected to the main supply for 20 min. If the 12 A current flow through the filament of the heater then what is the heat produced in the heater?


Given that

Current flow I = 12 A

Resistance R = 500 Ω

Time t = 20 min

The amount of heat produced by heater is Q = I²Rt

Q = 12² x 500 x 20 x 60

= 144 x 600000

= 86400000

= 84.6 MJ

Therefore, the amount of heat generated in the heater is 84.6 MJ.
