For an ideal MOSFET biased in saturation, the magnitude of the small signal current gain for a common drain amplifier is

The valid positive, negative and zero sequence impedances (in p.u.), respectively, for a 220 kV, fully transposed three-phase transmission line, from the given choices are

The Bode magnitude plot of a first order stable system is constant with frequency. The asymptotic value of the high frequency phase, for the system, is −180°. This system has

A balanced Wheatstone bridge ABCD has the following arm resistances:

R${}_{AB}$ = 1 kΩ ± 2.1% ; R${}_{BC}$ = 100 Ω ± 0.5% ; R${}_{CD}$ is an unknown resistance;

R${}_{DA}$ = 300 Ω ± 0.4%. The value of R${}_{CD}$ and its accuracy is

The open loop transfer function of a unity gain negative feedback system is given by
