In the circuit shown in the figure, the current i_L(t) is

Calculate the power consumed in a three phase AC circuit in which the load is delta connected. The system is supplied by a line voltage of 400 V and supplying a phase current of 25 A at a power factor angle of 30^o.

Obtain the transfer function C(s)/R(s) for the given signal flow graph.

The transfer function of a system is . For a unit step input to the system, the approximate settling time for 2% criterion is:

In a synchronous motor the armature current I_a = 200 A at unity power factor, for the same power what will be the armature current at a power factor of 0.5.

A resistance has nominal of 50 Ω. When it is measured, it’s value is 60 Ω. The % error is    .

For the arrangement shown in figure, the value of unknown resistance is:

the pu impedance of a line to 50 MVA, 132 KV base is 0.2 pu, the pu impedance to a 100 MVA, 165 KV will be:

A Ge transistor with β = 100 has base to collector leakage transistor is connected for current for I_B = 40 μA will lie:
