Series and Parallel Circuits
Type of Circuits
There are basically two types of circuits:
There are basically two types of circuits:
- Series Circuits
- Parallel Circuits
Series Circuits
In series circuits there is one path for current flow.
This is an example of series circuit
In series circuits there is one path for current flow.
This is an example of series circuit
Parallel circuits
In parallel circuits there could be two or more paths for current flow
This is an example of a parallel circuit
In parallel circuits there could be two or more paths for current flow
This is an example of a parallel circuit
We use standard symbols to draw electronic circuits or schematics.
Here are some of the standard symbols used.
