Function and operations of electric components

 

Transistor

Function- The transistor has 2 main functions; it can work as a switch and also work as an amplifier.

Operations- Transistors are composed of three parts – a base, a collector, and an emitter. The base is like a gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply.

When working as an amplifier, a very small amount of current may be used to control a large amount of current. With this same process the transistor can be used as a switch, but in this case there will be a certain amount of volts to open the gate, for example, five volts will be needed to open the gate, if it is more than five volts the gate will be open if it’s less than five volts the gate will stay closed.

Double Pole Double Throw Switch

Function- This switch is a pair of switches the work together.
