Draw a relay construction diagram and briefly explain the operation of a relay.
Define the terms normally open and normally closed.
Define the terms Set and Reset for relays.
Draw a latching circuit and interlocking circuit and briefly explain the operation of those two circuits.
Q. Discuss the disadvantages of an RC coupled amplifier? RC coupled amplifiers have a few disadvantages. The resistors use dc power and so the amplifier has low efficiency. The
Q. When the quantum step size δv and the step size of f (t) are the same as in , the quantizer is said to have a gain of unity. If, on the other hand, the quantizer has a gain of K
When a machine has more than two poles, only a single pair of poles needs to be considered because the electric, magnetic, and mechanical conditions associated with every other pol
Q. The unit impulse response h(t) of a linear system is h(t) = 5e -t cos(2t - 30°). Determine H(s).
Q. External Frequency Compensation of operational amplifier? For applications requiring a more extended high-frequency response, there are op amps with no internal compensation
Determine phase - voltage and power: A balanced star connected load is supplied from a symmetrical 3-phase 440 Volt system. The current in each of the phase is 40 Amp and lags
a. The antenna current of an AM broadcast transmitter, modulated to depth of 40% by an audio sine wave is 11 amp. It enhances to 12 amp as a result of simultaneous modulation by an
There are two practical ways of improving commutation i.e. of making current reversal in the short - circuited coil as sparkless as possible. These methods are known as (i) resista
Based upon the following inputs, propose the optimal course of action for this venture: Probability of success: 30%; probability of failure: 30%; base case probability: 40%
