Close the switch and store energy to open the switch
Basics of electrical switches
In an NC switch, the contacts are closed, thereby making electrical contact. Operating the switch causes the contact element to move and open the circuit. Fig. 2. Slow-make/slow-break pushbutton switches can be normally open (a) or normally closed (b). The two basic switch mechanisms are the slow-make/slow-break and the quick-make/quick-break

What happens when we close the switch?
The answer depends on the bulbs being used. Since nothing was said to the contrary, I think you should assume they are identical, having some constant resistance R. Figure out how the potential on one side of the branch with the switch compares to the potential on the other side of that branch when the switch is open.

6 FAQs about [Close the switch and store energy to open the switch]
What happens when a switch is closed?
The same The switch in the circuit shown has been open for a long time. At t = 0, the switch is closed. Once switch is closed, currents will flow through this 2-loop circuit. KVR and KCR can be used to determine currents as a function of time. Determine currents immediately after switch is closed.
What is the difference between open and closed switches?
A device designed to open or close a circuit under controlled conditions is called a switch. The terms ”open” and ”closed” refer to switches as well as entire circuits. An open switch is one without continuity: electrons cannot flow through it. A closed switch is one that provides a direct (low resistance) path for electrons to flow through.
What is a closed switch?
A closed switch is one that provides a direct (low resistance) path for electrons to flow through. Be the first to get exclusive content straight to your email. We promise not to spam you. You can unsubscribe at any time. What is Alternating Current (AC)?
What causes a switch to change from normally open to closed?
Normally open contact can change its state to a close position if the switch actuates by any type of energy, such as mechanical, pneumatic, hydraulic, or electrical. Thus, the actuation of the switch causes contact changeovers from the normally open to the closed position.
What happens after a switch is opened?
After a long time, the switch is opened, abruptly disconnecting the battery from the circuit. What is the current I through the vertical resistor immediately after the switch is opened? Why is there Exponential Behavior? Did we mess up? No: The resistance is simply twice as big in one case. After switch moved, which case has larger time constant?
How do you determine current when a switch is closed?
At t = 0, the switch is closed. Once switch is closed, currents will flow through this 2-loop circuit. KVR and KCR can be used to determine currents as a function of time. Determine currents immediately after switch is closed. Determine voltage across inductor immediately after switch is closed. Determine dIL/dt immediately after switch is closed.
