Electricity is the flow of electrons from one place to another. Electrons can flow through any material, but does so more easily in some than in others. How easily it flows is called resistance. The resistance of a material is measured in Ohms. principle purpose of this lecture is to present on Basic Electricity. Fuse is used as a safety device; prevents too much current flowing in circuit. Human being is a conductor of electricity so do not touch wires ,do not come into contact with water with electricity.
