1 -To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.

2-When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called heating effect of Electric Current. Example 1. A bulb becomes hot after its use for some time.This is because of heating effect of electric curren

4-Electromagnet.

Armature.

Spring. etc. 3- Solenoid valves are used to help control the flow of different liquids and gases. These valves are extremely important for the safe use of these materials
