Transistor Operation

What is the basic function of a transistor?

• Store and retrieve data

• Generate heat and light

• Convert mechanical energy into electrical energy

• Amplify or switch electronic signals and electrical power.

What are the three layers of a transistor called?

• anode, cathode, gate

• input, output, ground

• emitter, base, collector

• source, drain, gate

What is the difference between an NPN and PNP transistor?

• The main difference is the voltage rating.

• The main difference is the material used in the transistors.

• The main difference is the size of the transistors.

• The main difference is the direction of current flow.

What is the purpose of the base terminal in a transistor?

• To generate heat

• To amplify voltage

• To store charge

• To control current flow

What is the difference between the collector and emitter terminals in a transistor?

• The collector terminal emits charge carriers, while the emitter terminal collects charge carriers.

• The collector terminal and the emitter terminal have the same function in a transistor.

• The collector terminal collects charge carriers, while the emitter terminal emits charge carriers.

• The collector terminal controls the flow of charge carriers, while the emitter terminal collects them.

What is the symbol used to represent an NPN transistor in a circuit diagram?

• Triangle with arrow inward

• Square with arrow inward

• Circle with arrow inward

What is the symbol used to represent a PNP transistor in a circuit diagram?

• Triangle with an arrow pointing inward

• Triangle with an arrow pointing outward

• Square with an arrow pointing inward

• Circle with an arrow pointing inward

What is the role of biasing in transistor operation?

• To increase the distortion in signal processing.

• To establish desired operating conditions and ensure proper amplification and signal processing.

• To reduce the efficiency of amplification.

• To prevent overheating and damage to the transistor.

What is the difference between active mode and saturation mode in a transistor?

• The difference between active mode and saturation mode in a transistor is the level of emitter current.

• The difference between active mode and saturation mode in a transistor is the level of collector current.

• The difference between active mode and saturation mode in a transistor is the level of voltage gain.

• The difference between active mode and saturation mode in a transistor is the level of base current.

What is the purpose of a load resistor in a transistor circuit?

• To amplify the signal

• To regulate the voltage

• To protect the transistor from overheating

• To provide a controlled load for the transistor
