Class A amplifiers

Question 1

What is the biasing point of a Class A amplifier?

Answer 1

The biasing point of a Class A amplifier is in the middle of the load line.

Question 2

What is a key characteristic of Class A amplifiers regarding current conduction?

Answer 2

Class A amplifiers conduct current throughout the entire cycle of the input signal.

Question 3

What advantage does a Class A amplifier offer in terms of distortion?

Answer 3

Class A amplifiers provide low distortion due to continuous conduction.

Question 4

What is a disadvantage of Class A amplifiers in terms of efficiency?

Answer 4

Class A amplifiers have poor efficiency and generate heat due to continuous conduction.

Question 5

What type of applications are Class A amplifiers typically used for?

Answer 5

Class A amplifiers are often used in applications where signal fidelity is critical, such as in high-fidelity audio systems.
