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


When you walk into a dark room and turn the light on do the electrons travel all the way from the switch to the light?

When you turn on a light switch, the electrical circuit is completed, allowing electrons to flow. However, the electrons don't travel all the way from the switch to the light bulb; instead, the electromagnetic field propagates almost instantaneously through the circuit, causing the electrons in the wiring to start moving and create light. This means that the light turns on almost immediately, even though the individual electrons are moving relatively slowly.


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.


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.


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.

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?
