It is generally desired that a transistor should have ___________ input impedance
Answer & Solution
Correct Answer:
Option
C
Input impedance is like the resistance the amplifier presents to the signal source.
We generally want a high input impedance for a transistor amplifier.
Think of it this way:
A high input impedance means the amplifier doesn't load down the signal source too much.
If the input impedance is low, it would draw a significant amount of current from the source, reducing the signal strength and potentially distorting it.
Therefore, a high input impedance allows the amplifier to receive the signal with minimal disturbance to the source.
