When the electricity is converted to other forms of energy, a certain amount of energy is converted into heat energy.

This heating effect of current is termed joule heating or ohmic heating, or resistive heating.

[{"selector":"#anim-2ecafddf-43c1-49cc-b09e-6f750f4fdbf6","keyframes":{"opacity":[0,1]},"delay":0,"duration":1800,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-feb717af-5177-4b13-9efe-96be2361a57b","keyframes":{"transform":["translate3d(114.77986%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1800,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The heating effect is directly proportional to the amount of current passing and the resistance value of the materials.

[{"selector":"#anim-8546685f-befc-47ee-b462-6677f4bb4349","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-7dfcdf13-c349-43fc-b11b-afe1d1d5ab46","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

The heating effect is not concerned with the direction in which the electricity is passing.

Let us see the explanation of some applications of heating effects in our daily life:

[{"selector":"#anim-82da6133-c477-4419-a684-b54695b0715d","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-b63e7e6e-caf0-45b3-b2c7-d7047bcd669c","keyframes":{"transform":["translate3d(-125.09224%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Consider an electric bulb. Its filament is made up of tungsten.

[{"selector":"#anim-1a2bf4ba-28a4-4d0c-aeed-4d22bee95089","keyframes":{"opacity":[1,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-8c9da41e-c52f-4e8a-bdbb-383a74c58ffc","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

Upon passing the current, the filament generates heat and then illuminates the bulb.

[{"selector":"#anim-7bc3ab09-fb77-41c2-b6a1-4d3aed1c4d1a","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-06a6e0fb-8060-401d-8208-82badbe5ea4a","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

That means when the electricity is passed through tungsten which does not melt easily, it heats up to a certain temperature.

Consider an electric iron. Applying the heating effect of current, the iron breaks the flow of current when it reaches a certain temperature.

[{"selector":"#anim-95c42702-563b-4309-8ab7-52b10539e100","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-e793763a-1559-4c93-a6ad-492dce5f4f47","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

In the electric iron, we can see the red light turning on and off depending upon the temperature variation.

What happens where there is an excess amount of current passing through the electric circuit?

[{"selector":"#anim-2e47eb32-1938-4276-9503-0446a5a438f2","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-57131ce4-c0a8-47d5-b29a-ec158c44708d","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

The heat generated gets increased to an amount such that it melts the fuse. This helps in breaking the circuit.

[{"selector":"#anim-e165cfae-7db4-4c5c-a780-677a46515bb6","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-a55311e0-be35-4265-a9f9-ddbb59b02460","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

The amount of heat produced in a wire also depends on its material, thickness and length.
