## Electric Circuit

• A lot of appliances and devices in our houses uses electricity. Hence, electricity is an important element in our life.

## Electric Circuit

• Electricity is an important thing in human's daily life.

### Electric Component and Its Functions

• An electrical circuit is a complete circuit that allows electric current to flow through it.

• An electric circuit is made up of multiples components such as:-

### Electric circuit

• Connecting the bulb, dry cell and switch with wires will create one electric circuit.

• The switch is a component in the circuit that can connect and break the electric current in the circuit

• When the switch is closed, the electric current will flow and causes the bulb to light up.

• When the switch is opened, the electric current will not flow and causes the bulb not to light up.

### Why does not the bulb light up?

• There are multiples reasons why a bulb does not light up.

• For examples:-

 1. The bulb is broken 2. The dry cell does not have enough energy 3. Wrong-way of installing the bulb 4. The wire is not connected correctly 5. The switch is off

### Conductor and Insulator

• A conductor is a material that allows electric current to flow through it.

• An insulator is a material that does not allow the electric current to flow through it.

 Examples of conductor and insulators:-
