An electrical generator is a device that converts mechanical energy into electrical energy.

• It works on the principle of electromagnetic induction

• It consists of a rotor and a stator

• Examples include hydroelectric generators, wind turbines, and diesel generators

A resistance unit is a measure of the opposition to the flow of electric current.

• It is measured in ohms (Ω)

• It is used to calculate the amount of current flowing through a circuit

• Examples include resistors, thermistors, and potentiometers

The resistance unit of ohms is used to measure electrical resistance.

• Ohm is the SI unit of electrical resistance

• It is named after Georg Simon Ohm, a German physicist

• One ohm is equal to the resistance of a conductor in which a current of one ampere is produced by a potential difference of one volt
