A motor is an electrical device that converts electrical energy into mechanical energy, while a starter is a device that starts the motor.

• A motor consists of a rotor and a stator, which work together to produce rotational motion.

• Motors are used in a wide range of applications, from powering industrial machinery to driving electric vehicles.

• A starter is typically used to provide the initial burst of power needed to get ...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary windings, wrapped around a magnetic core.

• When an AC voltage is applied to the primary winding, it creates a magnetic ...read more
