Close the switch as soon as energy is stored

What happens when a switch is closed?

When the switch is closed, the current that points right-to-left for the inductor increases in the direction of the loop. As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: Einductor = − LdI dt

Which component ensures the current is zero after a switch is closed?

The component that ensures the current is zero just after the switch is closed is the inductor. Inductors do not like changes in current, since a change in current means the magnetic field linking the inductor is changing and this generates a back emf that opposes the change.

Why is the current zero after a switch is closed?

The reason is that there is inductance in the circuit as it is a loop of wire but of a very small value but significant value just after the switch is closed. The component that ensures the current is zero just after the switch is closed is the inductor.

What happens after switch S1 is closed?

Immediately after the switch S1 is closed: After current through the right resistor immediately after switch 2 is closed? IR = 0 B. IR = V/3R A circuit is wired up as shown below. The capacitor is initially uncharged and switches S1 Now very long time? VC = 0 The capacitor will become fully charged after a long time.

What happens if a switch status is changed?

As soon as the switch status is changed, the capacitor will act as short circuit for an infinitesimally short time depending upon time constant and after being in that state for some time it'll again continue to behave as open circuit.

What happens if a switch is not handled properly?

These events are called quenches, and they can do permanent damage if not handled properly. Even better, because the switch cannot throw infinitely fast, there will be finite lengths of time during which one contact is arbitrarily close to the other, so the voltage gradient arbitrarily high.
