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. With the help of the structures explain LCD. A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in fro
Q. A60-Hz, three-phase transmission line has a total per-phase series impedance of 35+j140 .Ifit delivers 40 MW at 220 kV and 0.9 power factor lagging, find: (a) The voltage, c
Q. The machine of Problem can be used as a motor. Let the terminals of the coil be connected to a voltage source of 1 kV rms. If the motor runs at 1800 r/min and draws a current of
The winch uses a 415 Volt 50 Hz AC motor, so both the up/down and run/stop controls actually operate +24V relays, whose contacts switch the 415Vac to the winch. The relays also pro
