Q: What is the primary function of a transistor?

Amplification and Switching — Transistors are fundamental for amplification and acting as electronic switches.

Q: Which of the following is NOT a terminal of a Bipolar Junction Transistor (BJT)?

Gate — Gate is a terminal of MOSFET, not BJT.

Q: What type of semiconductor material is typically used in the construction of transistors?

Semiconductor — Transistors are made from semiconductor materials like silicon or germanium.

Q: In a NPN transistor, the current flows from:

Collector to Emitter — The conventional current flow is opposite to electron flow, from collector to emitter.

Q: What does 'BJT' stand for?

Bipolar Junction Transistor — BJT is an abbreviation for Bipolar Junction Transistor.

Q: What is the region of operation where a transistor acts as a closed switch?

Saturation region — Saturation region means the transistor is fully 'on', acting like a closed switch.

Q: What is the region of operation where a transistor acts as an open switch?

Cut-off region — In cut-off, the transistor is fully 'off', acting like an open switch.

Q: Which of the following is a type of transistor?

NPN — NPN is a common type of Bipolar Junction Transistor (BJT).

Q: What are the two main types of transistors?

All of the above — All options present valid transistor types, with (c) being the primary distinction.

Q: The small change in base current can cause a large change in collector current. This property leads to what transistor functionality?

Amplification — This is the essence of transistor amplification.
