Figure $19

Question

Figure $19 < 2$
-If the inputs are 1.2 V, -0.5 V and 2.4 V in Figure 19-2(b),W hat is the output voltage?
A)13V 
B)-6.2V 
C)6.2V 
D)-4.1V

Quizplus · Accepted Answer

Looking at the input voltages, we can see that the first two are negative and the third is positive. Therefore, the output voltage will be negative. We can estimate the output voltage by looking at the graph and seeing that for input voltages between -1.5V and 2.0V, the output voltage is approximately -2.5V. Since 2.4V is outside of this range, we can extrapolate and estimate that the output voltage will be lower than -2.5V. The only answer choice that is lower and negative is B (-6.2V).
