Inverting Voltage Amplifier

Prelab:

Before the lab we determine what values of the resistor we need to have a gain of 2.

Lab:

First we got the actual values of the resistor

R1 = 2.15Kohms

R2 =  4.62Kohms

We use red and white wire from scope to provide the V+ and V- which are +5 and -5. We also connected the an input voltage that started from -3V to 4V with an increment of 0.5V. Then, using the DMM we measured the output voltage and recorded the values.
 Setup:

Sample Data:

Data and Chart:

Circuit Gain = - R2/R1
Circuit Gain = - 4.7/2.2
Circuit Gain = - 2.136

Using the measured and expected circuit gain, we calculated the percent error of  the circuit gain and the value we got is 0.468%. The percent error we calculated is fairly small so the measured value are acceptable.
