Why does a electric fan continue rotate for sometime even after the electric current is switched off?

∙ 9y ago
An electric fan continues to rotate for some time after the electric current is switched off due to inertia. Inertia is the tendency of a moving object to continue moving until a force acts to stop it. The fan blades have rotational kinetic energy that keeps them moving even when the power is turned off.

Why does an electric fan continue to rotate for some time even after the fan is switched off?
An electric fan continues to rotate after being switched off due to inertia, which is the tendency of a moving object to stay in motion. The fan blades still have momentum from the rotating motor, enabling them to keep spinning for a short period before coming to a stop.
Which wire in a cable is at or near to 0V and conducts an electric current whenever the appliance is switched on?
The wire that is at or near 0V and conducts an electric current whenever the appliance is switched on is the neutral wire. This wire completes the circuit and provides a return path for the current to flow back to the source.
Why does electric bulb become dim when electric heater in parallel circuit is switched on?
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
When the electric current is switched off the metal sticking to the electromagnet drops offexplain why this happens?
When the electric current is switched off, the electromagnet loses its magnetic field, causing the metal material to no longer be attracted to the magnet. This results in the metal dropping off from the electromagnet due to the absence of the magnetic force that was previously holding it in place.
How is an electromagnet switched on and of?
An electromagnet is switched on by passing an electric current through its coil, which generates a magnetic field. To switch it off, the current is simply disconnected, causing the magnetic field to collapse. This on/off switching allows for control of the magnetic force produced by the electromagnet.

What is a magnet created using electric current?
An electromagnet. Unlike other magnets it can be switched on and off.

When electric current is switched off the blades of the fan keep moving for some time. why.?
The blades of the fan keep moving due to inertia. Inertia refers to an object's tendency to resist changes in its state of motion. When the electric current is switched off, the fan blades still have momentum that keeps them moving until external forces like friction gradually bring them to a stop.
What causes an electric current to keep moving?
An electric current keeps moving because of the presence of an electric field. The electric field exerts a force on the charged particles (usually electrons) in the conductor, causing them to continue moving. In a closed circuit, the movement of electrons from the negative to the positive terminal of the power source ensures a continuous flow of current.
What actions causes current in an electric circuit?
Current in an electric circuit is caused by the movement of electric charges, usually electrons, through a conductor. This movement is typically initiated by applying a voltage difference across the circuit, which creates an electric field that pushes the charges. The current flow will continue as long as there is a closed path for the charges to move through.
What is the only time that electromagnets magnetise?
Electromagnets magnetise when an electric current flows through the wire coil, creating a magnetic field around the coil.
How did Oersted discover the relationship between an electricity and magnetism?
Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.
