# Joule Heating Calculator

Are you looking for a simple way to find Joule heating? Make use of our Joule Heating Calculator tool to get a rapid result. To obtain the joule heating value, simply enter the current flow, resistance, and time of the current flow in the fields and press the calculate button.

### Joules Law of Heating

The rate at which resistance in a circuit turns electric energy into heat energy is described by Joule's equation of heating. The link between the heat produced by an electric current flowing through a resistance is represented by Joule's first law.

### Joule Heating Formula

The following is the Joule heating formula **Q = I²Rt**

- Where, Q = amount of heat
- I = electric current
- t = time

When the current flow in the circuit and the current flow are stable, the amount of heat generated is proportional to the wire's electrical resistance; when the current supply and electrical resistance are constant, it is proportional to the square of the current flow through the circuit; and it is proportional to the time of flow.

### How to Calculate Joule Heating?

Along the lines are the simple procedures for calculating the heat produced by current flowing through a conductor.

- Step 1: Calculate the electric resistance in a conductor using time and current.
- Step 2:Multiply the electric current squared by the product of time and resistance.
- Step 3: The result is referred to as Joule heating.

### Joule Heating Example

**Question 1:**For 50 minutes, a heater with a resistance of 450 is connected to the main supply. What is the heat produced in the heater if a 15 A current flows through the heater's filament?

**Solution:**

Given:

Given:

Current flow I = 15 A

Resistance R = 450 Ω

Time t = 50 min

The amount of heat produced by the heater Q = I²Rt

Q = 15^2 x 450 x 50 x 60

= 225 x 1350000

= 303750000

= 303.75 MJ

Hence, the amount of heat generated in the heater is 303.75 MJ.

**Question 2:** Calculate the amount of heat energy released by a resistance of 10 Ω when a current of 5 A is passed through it for 7 minutes.

**Solution:**

Given:

Current flow I = 5 A

Resistance R = 10 Ω

Time t = 7 min

The amount of heat produced by the heater Q = I²Rt

Q = 5^2 x 10 x 7 x 60

= 25 x 4200

= 105000

= 105 MJ

Hence, the amount of heat is 105 MJ.
