Understanding Transistors

What are the three main components of a transistor?

• Base, Collector, Capacitor

• Emitter, Diode, Resistor

• Emitter, Base, Collector

• Collector, Resistor, Diode

What is the role of the emitter-base circuit in a transistor?

• It connects the base and the collector.

• It connects the emitter and the base.

• It connects the emitter and the collector.

• It connects the collector and the base.

What does forward bias mean in the context of a transistor?

• Both terminals connected to P-type

• Positive terminal connected to P-type, negative to N-type

• Both terminals connected to N-type

• Positive terminal connected to N-type, negative to P-type

In a transistor, which circuit is always reverse biased?

• Diode circuit

• Collector circuit

• Base circuit

• Emitter circuit

What happens to the bulb when switch S1 is off in the experiment?

• Bulb 1 lights up

• Bulb 2 lights up

• Both bulbs light up

• Neither bulb lights up

Why does the collector circuit not conduct if the base circuit is off?

• Because the collector circuit is shorted

• Because the base circuit controls the collector circuit

• Because the collector circuit is open

• Because the base circuit is reverse biased

What is the significance of the base being thin and lightly doped?

• It increases the resistance of the base

• It prevents current from flowing through the collector

• It allows more current to flow through the base

• It allows electrons to pass through easily

How does the base circuit control the collector circuit?

• By allowing electrons to pass through the base

• By decreasing the resistance

• By increasing the voltage

• By reversing the bias

Why can a transistor be used as an amplifier?

• Because it reverses the bias

• Because it decreases resistance

• Because it allows a small current in the base to control a larger current in the collector

• Because it increases voltage

What is the relationship between the current in the base and the collector?

• The currents are equal

• The currents are unrelated

• The current in the collector is always higher

• The current in the base is always higher
