This describes electricity. Whatever it powers, nothing flows if there is a gap in the circuit.

What types of energy can a closed circuit produce?
Light and heat energy
Why does the light turn on as soon as you flip the lightswitch?
The light is connected in a electrical circuit. The electricity will only pass through the circuit if the circuit is closed. A switch can open and close this circuit by simply not making contact with the next wire so the electricity can not be passed on. When you turn on the switch, the circuit gets closed again and the electricity will run through, so to the light. Because electricity has the speed of light (+-300 000 km/h) it will seems like the electricity reaches the light immediately. Plus the neutral travels through the filement of the bulb and down the switch wire giving an instant closed circuit when switch is closed
Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
Diagram of a closed circuit?
a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit
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.
In what type of circuit does eletricity travel when it does work?
Electric energy powers appliances such as a radio or light bulb. It travels in a CLOSE CIRCUIT.
When a light is on it is part of a scolde circuit?
when a light is on it is part of a scolde circuit
Do you need an open circuit or closed circuit for a garage door open light?
In order to illuminate the light, you need a closed circuit. It would be normally open, and closed to indicate that the door is open.
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.
A type of circuit that allows the light bulb to turn on?
a closed circuit
Is a free flowing path an example of a closed circuit?
It is a closed circuit if there is a load in the circuit (light bulb etc), otherwise it is a short circuit (+ to - on a car battery with a screwdriver)
Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
What types of energy can a closed circuit produce?
Light and heat energy
When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
Why does the light turn on as soon as you flip the lightswitch?
The light is connected in a electrical circuit. The electricity will only pass through the circuit if the circuit is closed. A switch can open and close this circuit by simply not making contact with the next wire so the electricity can not be passed on.

If you start at the negative end of the battery what will happen to the electrons when a closed circuit turn on a light?
When you start at the negative end of the battery, you start to lose electrons and the circuit is closed.
What does it mean when the circuit is opened?
Its means there is no continuity between point Ato point B. Ex. A light switch : When the switch is off it opens the circuit and electricity does not get to the light, when the switch is on the circuit is closed and the light will turn on.
