fuse
a type of sacrificial overcurrent protection device. Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. Short circuit, overload or device failure is often the reason for excessive current.
fuse holder
this where the fuse must be inserted to be protected from damages..
rocker switch
connects and disconnects electrical current or the current to a machine to make it operational or not. It is used on all sorts of large and small equipment and for lighting
.
diodes
this is used blocks current in one direction while allowing current flow in the other.
resistor
this is used to help control current flow in a circuit.
rotary switch
this is used to switch the position of the current…
plug and chord
this is used to run the electric current on the power supply.
transformer
this is used to transfer electrical energy from one circuit to another through inductively coupled conductors
