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.
What does electric current do?
Electric current is the flow of electric charge through a conductor. It produces various effects such as heating, lighting, and magnetism. In electronics, current is used to power devices and transmit signals.
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.
Who found heating effect of electric current?
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
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.
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).
Name any 5 electric appliances that make use of heating effects of electric current?
Five electric appliances that make use of the heating effects of electric current are electric stoves, electric kettles, hair dryers, toaster ovens, and space heaters. These appliances contain heating elements that convert electrical energy into heat energy through the process of resistive heating. The heat generated by the electric current is then used for cooking, boiling water, drying hair, toasting bread, or heating a room.
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.
Name Any two effects of electric current?
1. induces magentic field around the conductor.2.Generates heat in the conductor.3. Causes shock if flows through human body.AnswerThe three 'effects' of an electric current are its heating effect, its magnetic effect, and its chemical effect.It's magnetic effect (resulting in the force between parallel conductors) is used to define the ampere.
State the situations where heating effect of electric current is undesirable?
Heating effect of electric current is undesirable in electronic devices where overheating can lead to damage or malfunction. It is also undesirable in electrical transmission lines where energy loss due to heating reduces efficiency. Additionally, in some industrial processes where precise temperature control is required, excess heating can be a problem.
