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.
Q A beam containing two types of charged particles is moving from A to B. Particles of type I with charge +3q, and those of type II with charge -2q (where -q is the charge of an el

hi can you help me to create a dc to 3 phase ac circuit which can exceed at any point: 50V and 20A and 400W maximum. The output should be variable from about 0 – 25V per phase, wi
