Quiz 1 Analog Electronic 1

In an NPN transistor, the N regions are

• base and emitter
• base and collector
• emitter and collector
• base and ground

It is constructed with three doped semiconductor regions separated by two pn-junctions

• BJT
• OJT
• BUT
• BOT

BJT stands for

• Biomedical Junction Table
• Binary Justified Transistor
• Bipolar Junction Transistor
• Bipolar Junction Thyristor

The ratio of dc collector current (IC) to the dc base current (IB)

• alpha
• beta
• gamma
• theta

The region of transistor's operation when both junctions are forward-biased

• cutoff
• saturation
• partially off
• open

The emitter current is the sum of the collector current and the base current for both npn and pnp types of BJT

• True
• False
• Not sure

Emitter current is very small compare to base current and collector current

• True
• False
• Could be

Which of the following is not a terminal or region of a BJT?

• base
• collector
• drain
• emitter

Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of

• diode

• semiconductor

• conductor

• insulator

• superconductor

which statement is correct? (the dark circles represent the electrons)

• p-type of the diode is connected to the negative terminal.

• Electron moves across the p-n junction, makes the diode forward biased

• current will not flow in the circuit

• reverse biased circuit
