What is transistor and types?
A transistor is a semiconductor device used to amplify or switch electronic signals. Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs).

How is transistor connected in a circuit?
To connect the transistor as a switch in a circuit, we connect the output of the device that will switch on the transistor to the base of the transistor. The emitter will connect to ground of the circuit. And the collector will connect to the load that the transistor will turn on and the supply voltage of the circuit. The setup to set the transistor up as a switch is shown in the diagram below:
What is the difference between transistor and transformer?
A transistor can give power gain whereas transformer can not. In ideal transformer, the output power will be same as input power. A resonant tank circuit can also achieve current(parallel) or voltage gain(series), but not power gain. A transistor can take almost all shapes of input, a transformer can’t.
What is the difference between a transistor and a resistor?
A resistor has a fixed amount of resistance which doesn’t change, it also only has two terminals, an input and an output, the output depending on the input and the resistance. A transistor is like a resistor except it’s resistance can be controlled by a second input called the base input, also of note,…
Does voltage or current control a transistor?
A voltage or current applied to one pair of the transistor’s terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal.
