Q. Can you explain Noninverting Amplifier?
It is called "noninverting" because there is no sign inversion. A typical circuit is shown in Figure. With a finite op-amp gain Ao,
Since the ideal op amp draws no current,
i1 = i2
Also, as seen from Figure,
v2 = vi
In equating Equations, one gets
which is the gain of an ideal voltage follower. The same result applies if R1 →∞ (i.e., open circuit) for any finite R2.
in DC series generator we consider Eg=V+Ia(Ra+Rse).But in DC shunt generator why it is only Eg=V+IaRa and not Eg=V+Ia(Ra*Rsh/Ra+Rsh)
