When electric charges move through a wire, they lose some of the energy to the atoms in the wire. On receiving the energy, The atoms vibrate more and more causing the wire to heat up. Some of the Electric Energy is changed to heat energy. The higher the resistance the more the heat energy. The amount of heat generated is governed by Joule's first law:
Q = I2·R·t
where Q is the heat, I is the current, R is the resistance, and t is the time. If I is given in amperes, R in ohms, and t in seconds, the units of energy for the heat will be in Joules.

What effects of electric current is involved in the fuse breaking?
Heating Effect.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
Practical application of heating effects of electric current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
What effect of current is utilised in bulb?
Heating effect of electric current.
Enlist any four effects of electric current on conductor with one example of each?
Effects of an Electric current -1) Heating effect -e.g. - Heater / Geyser etc.2) Magnetic effect -e.g. - Electric Bell etc.3) Chemical effect -e.g. - Battery charging etc.4) Lighting effect -e.g. - Electric bulb etc.
State the situations where heating effect of electric current is undesirable?
negative effect of science .. with picture
What are the three effects of electric current?
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).
What are the advantage and disadvantages of heating effect of current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
Why the flow of current is not visible in wire?
flow of electrons is not visible.only it can be sensedAnswerCurrent can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
Can heating devices be made by passing an electric current through a conductor of?
Nichrome wire works.
