Transistors, How do they work?

What is one basic function of a transistor?

• To amplify or switch electronic signals.
• To store electrical energy.
• To increase the temperature of a circuit.
• To convert AC to DC power.

How many valence electrons does a silicon atom have?

• 2
• 6
• 8
• 4

What do we call the doping process where free electrons are added?

• n-type doping
• s-type doping
• c-type doping
• p-type doping

What appears to move in P-type doping?

• Holes
• Protons
• Neutrons
• Electrons

What is the result of reverse biasing a diode?

• The diode blocks current flow until breakdown occurs.
• The diode acts as a short circuit in reverse bias.
• The diode allows current to flow freely.
• The diode generates power when reverse biased.

What happens when you increase the base current in a transistor?

• The collector current increases.
• The voltage across the collector remains constant.
• The base current decreases.
• The transistor turns off completely.

How does a transistor function in digital electronics?

• A transistor acts as a switch or amplifier, controlling current flow to represent binary states in digital electronics.
• A transistor only amplifies sound signals.
• A transistor is used solely for storing data.
• A transistor functions as a resistor in circuits.
