Q1. Which one of the four options is true about the circuit shown below:

superposition theorem can be applied because it contains current source

reciprocity theorem can be applied

superposition theorem cannot be applied because it contains diode

superposition theorem can be applied

Q2. The power factor angle of a purely inductive circuit is

\(60^\circ\)

\(30^\circ\)

\(90^\circ\)

\(45^\circ\)

Q3. The EMF is induced only when there is ________.

moving conductor links with the magnetic flux

either magnetic flux linking with the coil changes or moving conductor links with the magnetic flux

magnetic flux links with coil changes

stationary conductor links with the stationary magnetic flux

Q4. A passive network has

current sources but no voltage sources

voltage sources but no current sources

both current and voltage sources

no voltage or current sources

Q5. Which of the following is NOT a true difference between EMF and potential difference (PD)?

EMF refers to source of electrical energy, while PD exists between any points in a circuit.

EMF is measured in an open circuit, whereas PD is measured in a closed circuit

PD is a cause of current flow, while EMF is the effect of current flow

PD is less than the EMF in the same circuit, whereas EMF is greater than the PD in the same circuit.

Q6. In a three-phase supply floating neutral is undesirable because it may lead to

unequal line voltages across the load

high voltage across the load

low voltage across the load

balanced voltage across the load

0 & – 4

0 & 4

– 4 & – 6

– 4 & 6

Q8. Adding a pole to a system transfer function in terms of compensator represents a ____________ compensator?

Lead

Lag

Lead-Lag

Lag-Lead

Q9. The transfer function of a control system is given as \(G(s)=\frac{1}{s^2+2s+1}\). The poles of the system are located at:

\(-1, -1\)

\(-2, -2\)

\(-1, -1, -1\)

\(-1, -1, -2\)

Q10. A system's transfer function is \( G(s) = \frac{K}{s(s+1)(s+2)} \). What value of \( K \) ensures that the system is critically damped?

\( K = 1 \)

\( K = 2 \)
