Special Problems on Transients Starter Quiz

If the following AC circuit shows transient free response, then L = ______mH.

where, V = 2 cos (2t – 135°)

Consider the following statements for the DC transient occurrence in the system:

1) Overvoltage condition occurs across the switch when the supply disconnects from a pure inductor.

2) Overvoltage condition occurs across the switch when the supply removes from the resistor.

3) Overcurrent condition will take place for sudden disconnection of supply from the resistor.

Which of the above statements will be correct?

Consider the following statements for the DC response of the circuit:

1) Smaller the time constant, faster the rate of decay of response.

2) Larger the time constant, faster the rate of decay of response.

Which of the above statement(s) are true?

In the given electrical circuit, the switch has been closed at t=0. Match List-I(current though different elements) with List-II(Value of voltage or current) and choose the correct answer using the codes below.

Find V0(t) for t > 0 for the electrical network shown in figure

Consider a circuit as shown in figure below:

Switch is connected to position 1 at t = 0 . It is given that in 3 sec, the voltage across capacitor become 60% of its steady state value. Steady state current in inductor is 10 A . If switch is connected to position 2, now if same linear network is connected shown below.

Find the expression of current i(t).

Find the capacitor voltage V1(t) shown in the below figure if the switch gets open at t=0 after being closed for a long time by using the data given in the electrical network.
