THE FLOW OF ELECTRIC CURRENT

Electricity is the flow of current from one point to another point.

CONDUCTOR AND INSULATOR

Conductors are objects or materials that allow electricity to pass through them e.g. metallic materials like nail, silver wire, copper wire, aluminum wire.

Insulators are object that do not allow current to pass through them. Examples are wood, plastics, glass, rubber band and non-metallic insulator.

SOURCES OF ELECTRICITY

Electricity can be generated from the following sources:

  1. Friction – Use of Galvanometer
  2. Magnetic – Use of Magnets
  3. Chemical Source – using Electrolyte
  4. Heat
  5. Biomass
  6. Solar
  7. Wind
  8. Hydro Electric
  9. use of Gas

COMPONENT OF A CIRCUIT

ELECTRIC CIRCUIT: An electric circuit is a pathway or a complete circle through which an electric current passes.

The component of an electric circuit are as follows:

  • Fuse: is a safety device used to control the amount of electricity that can pass through a point.
  • Switch: it is used to control electric current by enabling you to put off (stop) or put on (allow) light or current flow.
  • Key
  • Battery
  • Lamp etc.

USES OF ELECTRICITY

  1. Electricity gives us light.
  2. Electricity helps us in generating heat.
  3. It makes our home appliances work
