OPERATIONAL AMPLIFIERS 1

In this lab we will investigate how an op amp amplifies the voltage in order to obtain the voltage required. 

here is a picture of the original problem in the left side we have the sensor and in the right we have the op amp.

we will start this problem by first solving for the resistances in the right side here are the calculations. most of the calculations were done with the restrictions that are applied

we then proceed to solve for the left part of the problem. we also used the restrictions and the values found on the right part of the problem.

we also figured out the resistance by taking in consideration the power

we then proceed to calculate our Ry

after we were done we then proceed to measure our resistances and voltages 

and here was the actual circuit

after measuring here is a table of what we obtained 

 in conclusion we found out that a problem can be easier when broken into several pieces. we also found out that our measurements were not far apart from the theoretical notes. the op amp used was actually helpful in amplifying and inverting the voltage
