Question

What is the effect of electric current in electric fan

Answer 1

Answer:

When an electric current is supplied to an electric fan, its blades start moving. Along with moving of blades of fan, motor of electric fan gets warmed also. ... Thus, conversion of electrical energy into heat energy is called the HEATING EFFECT OF ELECTRIC CURRENT

Answer 2

Answer:

• When an electrical appliance is connected to an electric source and put on work, electric current, i.e. electrons start flowing between its two terminals. To put electrical appliance in working, electric source has to continue to supply the electric current, i.e. energy.

• Some of the electrical energy supplied is consumed in working of the electrical appliance, i.e. in useful work, and the rest of the electrical energy is used in raising the temperature of the electrical appliance.

• Example: When an electric current is supplied to an electric fan, its blades start moving. Along with moving of blades of a fan, the motor of the electric fan gets warmed also.

• If the electric current is supplied to an electric circuit with resistor only, the electric current is consumed in raising the heat of the resistor. This means that electric current dissipated entirely in the form of heat.

• We cannot use electrical energy directly. To use first electrical energy is converted into heat, light, or mechanical power.
• Thus, the conversion of electrical energy into heat energy is called the HEATING EFFECT OF ELECTRIC CURRENT.
• In other words, the generation of heat because of the dissipation of electrical energy, when electric current is passed through a conductor or resistor, is called the HEATING EFFECT OF ELECTRIC CURRENT.
