Electric Circuit

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

7.1

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:-
