BASIC ELECTRICITY 2
CONDUCTOR AND INSULATOR
The continuous flow of current is Electricity and it can either pass through or be hindered in its flow of electricity.
The Objects that allow the flow of electricity or that allow electric current to pass through are known as Conductor.
Examples are Iron, Copper, water, Urine and many more. They are all good conductors of electricity.
While objects or materials that doesn’t allow electricity to passed through are known as Insulators. Examples are plastic, rubber, wood, non-metallic insulator etc. They all prevents current from flowing.
The flow of electricity through Battery
Battery other known as cell are used to generate electricity, because current flows in and out through them;
The current flows in through the positive (+) charge side and comes out through the negatively charged (-) side. Also, they can be rechargeable and un-rechargeable. The rechargeable are known as Secondary cell while the un-rechargeable batteries are known as Primary cells.
How to generate electricity from a battery
- Take battery having both positive and negative sides
- Get a bulb
- Use a wire to connect the bulb and the battery in two different ways which are the positive and negative.
- Then the bulb glow.
These show that current flows through batteries either primary or secondary cells.
