Here is a pic of our pre lab, we chose 22kOhms for our resistors. The actual values however were, R1=21.5kOhm, R2=21.7kOhm R3=21.4kOhm. Since our R values should betheoretically equal, our Vout equation should be Vout=-(Va+Vb). Our values made since except for Va=1, the value should've been -1V but it was -1.94V. For the last two values the %error was huge because of the saturation of the Op-Amp. Here are our experimental values from our board Here's our circuit
Here are our values initials, however, most of them are wrong. The initial current we should've got is I=5V/1KOhm=.005 mA. And the L/R value should've been L/(2.2kOhm)=4.54*10^-7. And L/R*5=2.27*10^-6s=2.27 micro seconds. Here's the circuit we made. R1=.982 kOhm R2=2.16kOhm. was .98 mH Here's our graph of our circuit. Our 5*(L/5) was 4.17 micro seconds, so the percent error is 83.7C%. I'm assuming the reason for the huge error is due to the circuit not being set up properly.
