The S.I unit of charge is coulomb and measurement of electric current happens in units of coulomb per second which is‘ampere’. The current flows from the negative terminal to the positive terminal of the cell. This is a simple electric circuit. It has a lamp, a switch, and a cell. ...
Electrical current whose direction and value keeps changing is known as Alternating Current (AC). The value of AC current in one direction increases from ZERO to Maximum and fall down to ZERO and then in opposite direction it increases from ZERO to Maximum again and come back to ZERO. Due ...
