What happens when the circuit is complete and the switches are closed?
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
When a switch is on is a circuit open or closed?
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
What happens when you open a switch in a series crcuit?
A closed series circuit is one where the current flows through all devices in the circuit. Opening a switch prevents current from flowing in the circuit and it becomes simply an "open circuit". Any device that operates with current (light, LED, motor, etc) will no longer function.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
What happens to the flow of electricity in an incomplete circuit?
It stops flowing. An analogy to this is the kitchen faucet ... water is always "at the ready" behind the valve, ready to flow when it is enabled. Same is true in an electrical circuit - once the circuit is broken (valve closed in above analogy) the flow of electrons ceases. If there is a light bulb which is not on it is a open circuit. If the light bulb is still on it is parallel circuit which has lot of wires causes some of the lights to go on and some to go of.
Why is a light bulb not on when a switch is not closed?
A closed switch completes the electrical circuit, allowing current to flow through the light bulb and generate light. If the switch is not closed, there is an open circuit, meaning the current cannot flow and the light bulb does not turn on.
How does circuit stop flowing when light bulb switch is off?
The simplist answers is that electricity needs to complete a circuit fully. It stops flowing because there is no complete circuit. The switch is a device for opening and closing the circuit. When the switch is in the off position the circuit is said to be open and electricity cannot flow.
What is the function of the switch in circuit?
A switch simply opens a circuit, stopping the flow of electricity. For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb. With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.
When you open the switch what happen to the bulb?
If the switch is in the off position, the circuit will be broken and the electric current can't flow to the bulb, so the bulb will not light up.
Used to open and close a circuit?
A light switch
What do you mean by open and closed electric circuit?
An open circuit is one where the current is not able to complete the circuit. An example could be a light bulb connected to power but switched off, the circuit being broken by the switch, and considered "open." When flipping the switch On, it connects the power and the circuit is then closed.
When you turn on a light switch you an open circuit. What goes in the blank?
When you turn on a light switch you do not have an open circuit.
What are some examples of a closed circuit?
A connection from a power source, through a load and a return back to the power source. <><><> An example: electricity is supplied to the light switch on the wall through an insulated copper wire, even though the switch is in the off position electricity is present. There is another insulated copper wire going to the light bulb. When you flip the switch the circuit is completed and the light bulb comes on.
When the switch is closed it means that?
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
When you turn on a light switch in a room this open or close the circuit?
When you turn on a light switch in a room, it closes the circuit. This allows electricity to flow through the wiring to the light fixture, illuminating the bulb. Conversely, turning off the switch opens the circuit, stopping the flow of electricity and turning off the light.
What could you add to the circuit to control the bulb?
Switch
What is the function of switch in the circuit?
A switch simply opens a circuit, stopping the flow of electricity. For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb. With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.
