Test: Constructing Phase Trajectories - Electrical Engineering (EE) MCQ

Explanation: In liquid level and electrical system analogy, voltage is considered analogous to the head which can be pressure head that is the potential energy.

Explanation: The viscous friction co-efficient in force-voltage analogy, is analogous to resistance of the electrical circuit that can be found out mathematically.

Explanation: In force-voltage analogy, velocity is analogous to the current in force-voltage that is also called series circuit.

Explanation: In thermal-electrical analogy in which heat transfer in the wire or conductor can be related to the temperature.

Explanation: Mass, is analogous to the inductance in the force-voltage analogy in the series form as all the elements of the circuit are connected in the parallel.

Explanation: The transient response of the system is mainly due to stored energy as it is due to the initial conditions which is nothing but the stored energy.

Explanation: Actuating signal is the difference between the feedback signal and the reference signal and when both of the signals are equal then the signal is zero.

Explanation: Disturbance signal is also the reference signal only there can be multiple inputs in a control system or the other input is called the disturbance signal.

Explanation: The transfer function is different from the state space approach as the transfer function approach is similar to the LTI systems only while the state variable analysis is applicable to the non-linear time variant systems also.

Explanation: The transfer function can be obtained by using signal flow graphs from among these given methods.
