Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many external terminals does a transistor have?
A
One
B
Two
C
Three
D
Four
Explanation: 

Detailed explanation-1: -A transistor consists of 3 terminals. They are base, emitter and collector.

Detailed explanation-2: -Transistor – a three-terminal device for which the voltage or current at one terminal controls the electrical behavior of the other terminals. Bipolar Junction Transistor (BJT) – a three-terminal device for which the current at one terminal controls the electrical behavior of the other terminals.

Detailed explanation-3: -The name transistor comes from the phrase “transferring an electrical signal across a resistor”. Transistors are four-terminal semiconductor devices commonly used to amplify or switch electronic signals. Often one terminal is not used, therefore we will refer to tran-sistors as 3-terminal devices.

Detailed explanation-4: -The transistor has three legs, these are the base, collector and the emitter. The emitter is always connected to 0v and the electronics that is to be switch on is connected between the collector and the positive power supply. The base of the transistor is used to switch current through the collector and emitter.
