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.
LT Metering or Low Tension Metering The subsequent types of meters are generally used for LT consumers: Whole Current Meters i) Single phase meters ii) 3-phase
A moving coil galvanometer consists of a coil in a uniform magnetic field B o, suspended fro a fibre of torque constant C, current I produces a deflection O=nAB o i/c where n is
Why rhehostat is not used in the field of dc series motor
Q. Show NPN Common Emitter Amplifier? The common emitter configuration lends itself to voltage amplification and is the most common configuration for transistor amplifiers.
The block diagram for a 3-bit ripple counter is shown in Figure (a). Obtain a state table for the number of pulses N = 0 to 8, and draw a state diagram to explain its operation.
