Q. Illustrate Inductance with example?
An ideal inductor is also an energy-storage circuit element (with no loss associated with it) like a capacitor, but representing the magnetic-field effect. The inductance in henrys (H) is defined by
where λ is the magnetic-flux linkage in weber-turns (Wb·t), N is the number of turns of the coil, and Nψ is the magnetic flux in webers (Wb) produced by the current i in amperes (A). Figure (a) illustrates a single inductive coil or an inductor of N turns carrying a current i that is linked by its own flux.
The general circuit symbol for an inductor is shown in Figure (b).According to Faraday's law of induction, one can write
Q. Find load resistance and voltage? Let the amplifier block be connected to a current source at the input terminals, as shown in Figure(a), and to a load resistance R L at it
General configuration of cellular systems?
A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Φ/km and shunt admittance of j7.2ΦS/km. The line delivers 250MVA, at 0.6 lagging
(a) Let a unit impulse of current i(t) = δ(t) be applied to a parallel combination of R = 3 and C = 1/2 F. Determine the voltage vC(t) across the capacitor. (b) Repeat (a) for
Q. Sketch g m versus v GS for a JFET with I DSS = 10 mA, V P = 3V, V A = 100 V, and v DS = 10 V. See what happens if V A →∞. Also sketch r o versus v GS .
Q. Write a short note on the working of Darlington Amplifier? A Darlington Amplifier is one that is employing the Darlington pair of transistors. It is a
Q What is a clipper? Describe the operation of a biased clipper and combination clipper. The circuit with which the waveform is shaped by removing (or clipping) a portion of th
Half-wave rectifier: A half-wave rectifier will just only give one peak per cycle and for this reason and other reasons is only employed in extremely small power supplies. A f
A dc machine, operating as a generator, develops 400 V at its armature terminals, corresponding to a field current of 4 A, when the rotor is driven at 1200 r/min and the armature c
