This is an example for mutual inductance
Mutual induction an electric current is produced in the neighbouring coil when the magnetic field due to the other coil changes
Here
a. When switch turns off or on the flow of electricity through the coil just starts or ends this causes a deflection in magnetic field due to it
And due to mutual induction in the neighbouring coil electricity produces and bulb lights for a second
b. a long time after switch turned on current is passing through the coil is consistent so the magnetic field due to it
Also has no change
When there is no change no emf produced so bulb stays off

Problem 4 In the network shown below, the switch has been in the closed position for a long time. At t = 0, the switch is opened. Find an expression for V(t) for t>0, and find how much time is needed for the voltage across the capacitor to drop to 0.4094 V right after the opening of the switch t-0 0.3V 5uP

Specifically explain what happens to the current in each of the resistors and the charge on the capacitors? 2. What is the current supplied by the battery the instant after the switch is closed? What is the current supplied by the battery after the switch has been closed for a very long time?
A circuit is constructed with two resistors and one inductor as shown in the Figure below. The values for the resistors are: R1 = 2.50 and R2 = 4.5 0. The battery voltage is V = 12 V. The switch S is initially open. S R V R2 L 000 1) After the switch has been opened a long time, it is closed. What is the magnitude of the voltage across L immediately after the switch is closed?

In the circuit shown in (Figure 1) switch Si has been closed a long time while switch S2 has been left open. Then S2 is closed at the same instant when S1 is opened.Part A Just after S2 is closed, the current through the resistor is 12.0 A and its rate of decrease is di/dt = 36.0 A/s. How long does it take the current to decrease to Figure 1 of 1 6.00 A, one-half its initial value?
