Electric circuit is a path of electric current
For Ex. : Lamps, Battery, Generation
Earth Lead : The current directly goes into earth.
FUSE: This is used to protect circuit from over Current or short circuit.
Mini Circuit Breaker: It is used to break the circuit or cut the current flow.
RCD: It compares from live and neutral wires.
Series: In this circuit the whole current flows in each component.
Parallel: In this circuit, the whole voltage flows in each component.
Series-Parallel: This circuit has all components connected from end to end.
