How does it work?!
Currents are produced by the pressure from cells or batteries(a group of cells)...
The electricity flows out from one terminal or contact and back into the other...
One terminal is a positive pole and the other is a negative pole...
The positive pole attracts particles from the negative pole...
When the particiles or electrons are attracted to one another, it makes electricity!
How many types of electricity are there?!
Two....
Static and current
