Correct Answer

-100 mV

Explanation

Input to non-inverting op-amp is -10 x 10^-6 x 10³ = -10 mV.

Therefore output = The output V0 in figure is -100 V -100 mV 10 V 10 mV Input to non-inverting op-amp is -10 x 10-6 x 1 = -100 mV.

1. If an amplifier with gain of - 1000 and feedback factor ? = - 0.1 had a gain change of 20% due to temperature, the change in gain of the feedback amplifier would be
Options
A. 10%
B. 5%
C. 0.2%
D. 0.01%

Correct Answer: 0.2%

Explanation:

As we know, Gain with feedback

A = - 1000, ? = -0.1 .

Correct Answer: conductivity
