ELECTRICAL CIRCUIT:

              An  Electric  Circuit is  a  path  of interconnected  electrical  components in  which  electrons
               flow from one end of source to the other end of source.

              If the circuit is incomplete or broken, the current doesn’t flow. This type of circuit is called an

               Open Circuit.
              If the circuit is complete, the current flows. This type of circuit is called a Closed Circuit.

              A circuit usually contains a Power Source, which is the source of electrons and a Load,

               which is the electrical appliance, like a bulb, needing electricity to run.
              A switch or key in the circuit is used to make or break the circuit to start or stop current

               flow.
              Electric Circuit Diagram is a pictorial representation of a circuit with electrical symbols for

               its corresponding parts.
