An electric circuit is a continuous closed pathdiscontinuous pathcontinuous open loop along which current flows from the positive terminalnegative terminal to the negative terminalpositive terminal of the battery. It has a network of electrical components through which electronsneutronsprotons flow.

 

 

The SI unit of the electric current is amperewattvolt. The unit is defined as the amount of current flowing through any cross-section of a conductor when one ampereone coulombone volt of charge flows through it in one hourone minuteone second.
