First Order Transient - 1 Starter Quiz 5

Calculate the time at which the current in the given circuit will attain 96% of its final steady state value. (Given R=8Ω, L=2H)

In the parallel circuit shown in figure, the applied voltage V (magnitude only) is _______ V, where V_AB = 48.3 ∠30^o V

An RC series circuit, initially at rest has a step voltage signal. The response V_C(t) across C is V_C(t) = 2 – 2e^–4t. If now, there is an initial voltage at C of 4 V, then the response V_C(t) is given by

A voltage source of 60∠-30^o V is connected in parallel across a choke of resistance 4 Ω and inductive reactance of 3 Ω. If an impedance, Z = 6 – j8 is connected parallel across the choke, then the magnitude of the current supplied by voltage source is ………A.

Calculate the induced emf (in V) in the inductor of a series RL circuit having inductance of 1.8 H and resistance of 90 Ohms after 20 milli-seconds, when supplied by a 20 V DC source.

A parallel RC circuit is excited at t = 0 by closing a switch as shown in figure below. Before connecting the switch, capacitor is discharged. Find the value of  at t = 0⁺.

For the network shown below, switch is opened at t = 0, Before t = 0 switch was closed and you can assume that network was in steady state. The value of at t = 0⁺ will be ______ V/sec.
