Transistors

What are the two types of transistors discussed?

• LMN and OPQ

• 123 and 456

• ABC and XYZ

• NPN and PNP

What happens when the control switch is open in an NPN transistor?

• Current flows freely

• The transistor lights up

• The transistor explodes

• The depletion layer blocks current

What allows a larger current to flow in a transistor?

• A large current through the base

• A small current through the base

• A broken base

• No current through the base

What is the role of the base in a transistor?

• It is the control terminal

• It is the output terminal

• It is the power source

• It is the ground

What is the function of the emitter in a transistor symbol?

• It points to the positive material

• It points to the negative material

• It points to the power source

• It points to the ground

What is the main purpose of a transistor in an electrnoic circuit ?

• To store electrical energy

• To amplify or switch electronic signals

• To convert AC to DC

• To act as a resistance in the circuit.
