Question

if the feedback resistor in an inverting amplifier opens, the gain becomes zero.
select one:
○ true
○ false

Explanation:

The gain formula for an inverting amplifier is $A_v = -\frac{R_f}{R_{in}}$. When the feedback resistor $R_f$ opens, its value approaches infinity. Substituting this into the formula gives $A_v = -\frac{\infty}{R_{in}}$, which means the gain approaches infinity (not zero), making the statement false.

Answer:

False
