Noninverting Amplifier Exp

The input signal is in the non-inverting input of the OpAmp. The inverting input of the OpAmp is connected to the reference potential - ground. The noninverting amplifier increases voltage, i.e. multiplies voltage to a positive constant: Vout=Vin*(R1+R2)/R1. The gain of the scheme is always grater than 1: Gain=1+R2/R1. The input resistance is: Rin=∞. The output resistance is: Rout=0.
