Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An electric motor is a device that uses an ____ current to turn an ____
A
mechanical current to turn an axle
B
electrical current to turn an axle
C
mechanical current to turn a rod
D
electrical current to turn a rod
Explanation: 

Detailed explanation-1: -An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device.

Detailed explanation-2: -An electric motor is a device that uses an electric current to turn an axle. An electric motor transforms electrical energy into mechanical energy.

Detailed explanation-3: -An electric motor is a device used to convert electricity into mechanical energy-opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.

Detailed explanation-4: -Electric motors are used in electric fans, mixers, water pumps, washing machines, etc.

Detailed explanation-5: -An electric motor converts mechanical energy into electrical energy.
