I just setup a non-inverting circuit using an tlc272 op amp cp. But I am not sure of what the op amp does. I am using a potentiometer to control the voltage supply. I believe there is suppose to be some type of gain but when check the amount of current flowing through the circuit (using multimeter), the amount of current in the output is equal to the amount of current in the in the input. I have connected the positive input to 9 volt battery and the negative input to ground.
I was wondering if some could explain what op amps are used for?
