Understanding Transistors

What is a transistor?

• A transistor is a device that stores electrical energy.

• 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 type of battery used for power storage.

Who invented the transistor?

• John Bardeen, Walter Brattain, and William Shockley

• Nikola Tesla

• Thomas Edison

• Alexander Graham Bell

What are the main types of transistors?

• Optical Transistors

• Transistor Amplifiers

• Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs)

• Integrated Circuit Transistors

How does a transistor work?

• A transistor acts as a switch or amplifier by controlling current flow using a small input current.

• A transistor is a type of battery that stores energy.

• A transistor only works in digital circuits.

• A transistor generates electricity from heat.

What is the role of a transistor 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.

• To measure current flow in a circuit.

• To store electrical energy in a circuit.

What is the difference between a BJT and a FET?

• FETs are current-controlled devices using both charge carriers.

• BJTs are current-controlled devices using both charge carriers; FETs are voltage-controlled devices using one type of charge carrier.

• BJTs are voltage-controlled devices using both charge carriers.

• BJTs use one type of charge carrier while FETs use two.

In what applications are transistors commonly used?

• Transistors are used for cooking appliances.

• Transistors are primarily used in mechanical devices.

• Transistors are only found in analog clocks.

• Transistors are commonly used in amplifiers, switches, digital circuits, and signal modulation.

What is the significance of the transistor in modern electronics?

• Transistors are primarily used for analog signal processing.

• Transistors are crucial for enabling miniaturization and functionality in modern electronic devices.

• Transistors have no impact on the speed of electronic devices.

• Transistors are only used in large industrial machines.

How can transistors be used as switches?

• Transistors are used exclusively in analog circuits.

• Transistors require mechanical parts to function as switches.

• Transistors can only amplify signals, not switch them.

• Transistors act as electronic switches by controlling current flow based on input voltage.

What are the advantages of using transistors over vacuum tubes?

• Transistors are smaller, more efficient, reliable, faster, and cheaper than vacuum tubes.

• Transistors are larger and more fragile than vacuum tubes.

• Transistors require more power to operate than vacuum tubes.

• Transistors are more expensive and less efficient than vacuum tubes.
