The light will come on instantly (incandecent bulbs only), because current travels faster than the speed of light (theory).

If a light bulb is burned out and the switch is on are you still using electricity?

A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it. If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on It may still use power if it is a lighted switch. Find a licensed electrician at www.contraxtor.com


Can you use g9 bulb on a dimmer switch?

It is generally not recommended to use a G9 bulb on a dimmer switch unless the bulb is specifically marked as dimmable. Using a non-dimmable bulb on a dimmer switch can cause flickering, buzzing, and even damage to the bulb or the dimmer switch. Always check the bulb packaging to ensure it is compatible with dimmer switches before using them together.


Will it cost you electricity if you leave your switch on but with no bulb?

No In a standard house lamp, if the bulb is missing the circuit is broken in the same way as if the light switch were off. It is not very safe, however, to leave a lamp like this. A child or pet could complete that circuit easily by touching the two connectors in the socket and receive a very bad shock.


Why it is possible to light the bulb even though only one wire is used?

A complete electrical circuit is formed even with just one wire because the wire provides a path for the flow of electrons from the power source to the light bulb and back. This flow of electrons allows the bulb to light up. In this scenario, the bulb is acting as a resistor completing the circuit.


Window switch works but does not light up?

If the window switch is functioning properly but not lighting up, it could be a faulty LED bulb within the switch. You may need to replace the switch to resolve the issue. Ensure to check the wiring connection as well to rule out any loose connections.

Does electricity flow through a light when the light is turned off?

The OFF position on the light switch interrupts the flow of electricity to the light bulb. If the switch is ON, there is always electricity at the light socket, even when the light bulb is removed. if the lamp is still pluged in electricity is still flowing through the lamp even if it is off or on


Could a bad ignition switch on a 1995 Harley softail custom prevent the brake light from coming on even though the tail light is on?

Try checking the bulb, the brake light bulb may be blown.

My halo light on 00 dodge ram for the key switch doesn't light up even though the bulb has been replace?

If the bulb has been replaced then there could only be one solution. The fuse for the light is blown or has become loose.


What is an example of a 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.


How does removing a bulb or opening and closing the switch affect a parallel circuit?

it is because the energy flows through the switch and it makes the light bulb turn on and if the switch is open the energy will not flow it will stay in the place the switch begins


What are some examples of a closed circuit?

Where is Thomas Edison's light bulb?

Thomas Edison's light bulb burned for a number of years even after his death. The light bulb is currently located at the Menlo Park Museum.


What is the difference if a switch is before or after a bulb in a circuit?

It is a safety concern. With the switch before the bulb, the bulb is completely isolated from the potential source when the switch is turned off. With the switch behind the bulb, even if the switch is turned off, the potential source is still at the bulb. If any of these lamp holder parts touch the ground when removing the bulb the circuit will short out and trip the breaker. If you are grounded and touch any of the lamp holder parts you will get a nasty shock.
