For the circuit as shown, consider that switch S1 has been in position B for a very long time and switch S2 has been open all the time. At time t = 0, the switch S1 moves to position A and switch S2 closes instantaneously. What is the value of Vout of t = 0+, assuming initial charge on C = 0?

For the circuit as shown, consider that switch S1 has been in position B for a very long time and switch S2 has been open all the time. At time t = 0, the switch S1 moves to position A and switch S2 closes instantaneously. What is the value of Vout of t = 0+, assuming initial charge on C = 0? Correct Answer 0 V

The circuit diagram at time t = 0 is as shown below.

The current flows through inductor, IL (0) = 10 A

The voltage across the capacitor, Vout = 0 V

At t = 0+, the circuit diagram is as shown below

As inductor can’t allow the sudden change in the current, the current flows through the inductor = 10 A

As the capacitor can’t allow the sudden change in the voltage, the voltage across the capacitor = 0 V

A container of 425 liters was filled with chemicals through two pipes. The first pipe was kept open for 5 hours more than the second pipe. If the first pipe remains open for as long as the second pipe remains open, and the second pipe remains open for as long as the first pipe remains open, then the quantity of chemical filled by the first pipe was half the quantity of chemical filled by the second pipe. If both the pipes are opened simultaneously, the tank will be filled in 17 hours. For how long was the second pipe open?
