B. Infinity
C. One
D. Greater than one
Answer:A
What will be the voltage drop across the source resistance of differential amplifier when connected in open loop configuration?
A. Zero B. Infinity C. One D. Greater than one
Explanation: The source resistances are normally negligible compared to the input resistance. Therefore, the voltage drop across input resistors can be assumed to be zero.
