6. Types of electric circuits

We have discussed about electric circuits in the previous section. Let us now discuss the types of electric circuits. Electric circuits are of three types, they are

Simple circuit:

  

The above circuit is simple because it has simple electrical elements like a battery, bulb and switch.

  

Current is the same in all the elements in the case of series connection. If any one of the elements is damaged or disconnected, then the entire circuit will not work.

 

  

In the above diagram, all three LED's are connected in the form of a chain, so it forms a series connection. And, the current flow in all the LEDs will be the same.

  

Parallel circuit:

Thus, a parallel circuit has two or more paths for the current to flow through. If any element is damaged or disconnected, other elements will work properly without any disruption.

 

 

In the above diagram, all three LED's are connected in the form of a parallel connection, so it forms a parallel connection. And, the current flow in all the LEDs will not be the same.

 

Some of the electric symbols:

 

1. Electric cell
2. Battery
3. Switch-open
4. Switch-closed
5. Electric bulb
6. Connecting wires
