What are the three factors on which the heat produced by an electric current depends also state how the heat produced depends on each factor?

1 Answer

• Heat produced by an electric current depends on the following factors:
• (i) Heat produced is directly proportional to square of current.
• (ii) Heat produced is directly proportional to resistance.
• (iii) Heat produced is directly proportional to the time for which current flows.

What are the three factor of electric current?

1)Electric current, 2)resistance of the heating element ,3)time taken to consume electricity .

What are the factors on which heat produced depends?

The factors on which the amount of heat produced depends on the below:

• Electric current,
• Resistance to heating element and.
• Time period to utilise the energy.

What are the three factors on which the amount of heat produced in wire depends?

The heat produced in wire depends on its material, length, and thickness.

How is heat produced by an electric current?

When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. The reason for this change in temperature is the transformation of some electric energy passing through the conductor into heat energy.

What causes heat in electrical circuits?

In metal conductors, electrical current flows due to the exchange of electrons between atoms. As electrons move through a metal conductor, some collide with atoms, other electrons or impurities. These collisions cause resistance and generate heat.

What are the 3 factors of heat?

In This Article

• Temperature difference. The greater the difference in temperature between the two ends of the bar, the greater the rate of thermal energy transfer, so more heat is transferred.
• Cross-sectional area. A bar twice as wide conducts twice the amount of heat.
• Length (distance heat must travel).
• Time.

What factor does the amount of heating in an electric conductor by electric current depend on?

The resistance of the conductor. A higher resistance produces more heat. The time for which the current flows. The longer the time the amount of heat production is high.

What is an electric current made up of?

electrons
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

What is heating effect of electric current give an example?

This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called the heating effect of current. Example, Electric iron, electric toaster, water heaters, etc., work on this effect.

What is the effect of electric current?

Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect. Note:we have discussed briefly about the effects of current. You need to memorize the effects namely heating effect, magnetic effect and chemical effect.

How is heat produced by an electric current related to resistance and the magnitude of the current?

Answer: When an electric current is passed through a high resistance wire (like nichrome wire), the resistance wire becomes hot and produces heat. This is called the heating effect of current. When an electric current passes through a high resistance wire, the electric energy gets converted into heat energy.

What are the factors on which the heat produced by current depends?

State three factors on which the heat produced by an electric current depends. How does it depend on these factors? (i) Heat produced is directly proportional to square of current. (ii) Heat produced is directly proportional to resistance. (iii) Heat produced is directly proportional to the time for which current flows.

What are the factors that affect the temperature of an electric conductor?

Heat produced by electric current passing through a conductor depends upon 4 factors and not 3, that is current, resistance of the conductor, time duration and the medium in which the conductor is placed. Because temperature rise = I*I*R*t, where, I = current, R = resistance and t = time duration and…

What happens when current flows through a conductor?

When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat.

How do household electrical appliances convert electrical energy into heat?

Most household electrical appliances convert electrical energy into heat by this means. These include filament lamps, electric heater, electric iron, electric kettle, etc.
