Electrical Circuit 
It is a conducting loop in which a current can transfer electrical energy from suitable source to a useful load
Source or supply 
It is a part of circuit that provides the voltage needed to force current through the circuit
Conductors 
It is a part of circuit where the current travels
Load 
It is a part of circuit in which it converts electrical energy
Control Device 
It is a part of circuit that is use to open or close the circuit
Protection Device 
It is a part of circuit that its interrupts the circuit in case of malfunction
Resistors in Series 
The resistors are connected end-to-end in s line to form a single path through which current can flow
