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:-
|
| |
 |
| |
|
| |
|
|
| |
- 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.
|
| |
|
|
| |
| 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

- 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.
