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. Amplifiers with Feedback? Almost all practical amplifier circuits include some form of negative feedback. The advantages gained with feedback may include the following: •
What is the properties and application of iron?
Q. Find v o in the circuit shown in Figure by using the ideal op-amp technique.
The no-load and blocked-rotor tests on a three phase, wye-connected induction motor yield the following results: • No-load test: line-to-line voltage 400 V, input power 1770 W,
Why do potential barriers breaks when a breakdown voltage is application to semiconductor
1. The coil remaining stationary with respect to the flux, the flux varies in magnitude with time. Since no motion is involved, no energy conversion takes place. Equation gives the
