RC Circuits
Both switches are initially open, and the capacitor is uncharged. What is the current through the battery just after switch S 1 is closed? 2R 1) I b = 0 2) I b = E /(3R ) +-ε C R 3) I b = E /(2R) 4) I b = E /R I b +-+-S 2 S 1 Capacitor acts like a wire the instant the switch is instant the switch is closed: I /(2R) Physics 102: Lecture 7
Electrical Switches
Momentary switches can be either "normally closed" or "normally open" switches. With a normally open switch the circuit is open until the user pushes the button. An example of a normally open switch would be your front door bell button. With a "normally closed" switch the circuit is complete ( or closed) until the user pushes the button.
What Happens When a Switch is Opened?
Toggle Switches: These switches have a lever that is flipped up or down to open or close the circuit. They are commonly found in household appliances and lighting fixtures. Push-button Switches: These switches are activated by pressing a button. They are often used in doorbells, alarm systems, and other applications where momentary contact is

Energy-efficient since no power flows in the default state. Ideal for applications requiring momentary actions. What is a Normally Closed (NC) Contact? A normally closed contact is one where the circuit remains closed (i.e., complete) in its default state. Current flows through the circuit until the switch or relay is actuated.

Extending the bolt not only locks the switch in the open position, but it also breaks electrical motor contacts integral to the lock and permits the key to be removed. With the key, the operator can then open the lock on the switch door. This scheme gives positive assur-ance that the switch is open and cannot be closed with the door open.

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.

How does an open switch and a closed switch affect a circuit?
Open circuits are often created by design. For instance, a simple light switch opens and closes the circuit that connects a light to a power source. Closing the switch completes the
6 FAQs about [Open the switch to store energy or close the switch]
What happens when a switch is open?
When the switch is open, a gap is created in the electric circuit, which breaks the flow of electric charge, and the bulb does not light up. When the switch is closed, there is no gap in the electric circuit, electric charge can flow, and the bulb lights up.
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.
How can you tell if a switch is open or closed?
To determine if a switch is open or closed, observe the circuit. If the switch is open, the circuit is broken with a gap, preventing electric charge from flowing. The bulb will not light up in this case. If the switch is closed, the circuit is complete, allowing electric charge to flow and light up the bulb.
What happens when a normally closed switch is activated?
When the normally closed switch is in its default position it allows current to flow through it. When the switch is activated or compressed it opens the circuit and causes the current to stop flowing. Activating a normally closed switch can cut all power to a machine or piece of equipment. Where are Normally Closed Switches Used?
What happens when a light switch is closed?
Open circuits are often created by design. For instance, a simple light switch opens and closes the circuit that connects a light to a power source. Closing the switch completes the conductive path in this flashlight, allowing electrons to flow. How does closing the switch affect the circuit? If the switch is closed, the light operates.
What happens if a switch is closed?
If the switch is closed, the light operates. When a second 60 watt bulb is added to the circuit in parallel with the first bulb, it is connected so that there is a path to flow through to the first bulb or a path to flow through to the second bulb. How does a switch effect a circuit?
