Question 1

A 5 Ω resistance and 20 H inductance is connected in series across a battery. At the instant of closing the switch, the current increases at the rate of 4 A/s. Find the supply voltage in the above-mentioned case.

Question 2

Calculate the maximum power (in Watts) which can be delivered by the following circuit.

Question 3

The switch has been in position 1 for a long time and abruptly changes to position 2 at t= 0.

If time t is in seconds, the capacitor voltage Vc (in volts) for t>0 is given by

Question 4

In the circuit shown below, Vs is a constant voltage source and IL is a constant current load.

The value of IL that maximizes the power absorbed by the constant current load is (Al

Question 5

In the figure shown, the capacitor is initially uncharged. Which one of the following expressions describes the current I(t) (in mA) for t > 0?
