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. Why depletion MOSFET is known as "normally-on MOSFET" ? Draw the symbol of n-type and p-type depletion MOSFET. In depletion type MOSFET the drain current flows even when VGS
Q. For a parallel-plate capacitor with plates of area A m 2 and separation d m in air, the capacitance in farads may be computed from the approximate relation Compute the
a. Determine the power flow diagram for a DC generator. b. A shunt wound DC generator delivers 496 A at 440 V to a load. The resistance of the shunt field coil is 110? and that
Electromagnetic torque The torque is given by the force on the armature winding multiplied by its radius. Force on a conductor in magnetic field B is: F=B.I.L so, T=B
