Exploring the World of Transistors

What is a transistor?

• A transistor is a type of battery used for storing power.

• A transistor is a semiconductor device used to amplify or switch electronic signals.

• A transistor is a type of resistor used to limit current.

• A transistor is a mechanical device for converting energy.

Name one type of transistor.

• Bipolar Junction Transistor (BJT)

• Operational Amplifier (Op-Amp)

• Field Effect Transistor (FET)

• Diode Transistor (DT)

How does a transistor work?

• A transistor only works in digital circuits.

• A transistor is a type of battery.

• A transistor generates electricity from heat.

• A transistor acts as a switch or amplifier by controlling current flow between its terminals based on an input signal.

What is one use of transistors in everyday life?

• Storing data in computer memory.

• Generating electricity in power plants.

• Amplifying electronic signals in devices like radios and televisions.

• Displaying images on screens.

What symbol represents a transistor in a circuit?

• A rectangle with four lines

• Transistor symbol is a circle with three lines (for BJT) or a similar variant for FET.

• A triangle with a dot

• A square with two lines

Can you name a device that uses transistors?

• Television

• Light bulb

• Calculator

• Radio

What is the role of a transistor in a circuit?

• To store electrical energy in a circuit.

• To increase the resistance in a circuit.

• To convert AC to DC voltage.

• The role of a transistor in a circuit is to act as a switch or amplifier.

How do you identify a transistor in a diagram?

• Check for a single terminal with a circle around it.

• Look for two terminals and a resistor symbol.

• Look for three terminals and specific symbols in the diagram.

• Identify by the color of the wires connected.

Why are transistors important in technology?

• Transistors are not relevant to modern technology.

• Transistors are used only in computers.

• Transistors are essential for controlling electrical signals in electronic devices.

• Transistors are primarily for storing data.
