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.

Ac power has significant practical advantages over dc power in generation, transmission, and distribution. One major drawback of the single-phase circuit is the oscillatory nature
Q. Consider the op-amp circuit of Figure. Sketch the waveforms of v S and v o , if v S is a sinusoidal voltage source with a peak value of 2.
Quite often an amplifier is used as a component of an amplifier circuit. Consider the amplifier circuit shown in Figure, which contains an amplifier block as an internal component.
