<h3>Functions of the parts of a Circuit.</h3>
The wire helps in the distribution of the electric current from the power 
source in order to ensure it gets to the load.
The battery contains compounds which is responsible for providing the 
energy required to power up the load. 
The load could be a bulb, fan etc and is the final destination of the electric 
current. The electric current powers up the load and makes it functional.
The switch helps to regulate the flow of electric current and has an 'on and 
off button' to prevent energy wastage when not in use.
