because you are switch the hot leg, so it can be turn on an off.

What effect will occur if the intermediate switch is replaced by a double pole switch?
The circuit will not work. In a three way lighting circuit system the middle switch needs to cross the traveller wires to be effective. A double pole switch in the circuit will just open both traveller wires and disrupt the current flow in both wires. No current flow, no lights.
How does a torch work for kids?
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.
A simple model of a circuit?
An electric circuit is a closed loop that allows a flow of electrons to begin from a source of the electrons and return to the same source. Some of the energy carried by the current from the source may or may not be released to perform useful work. Because of the resistance of the materials in the circuit, some of the energy carried by the current is always lost as heat emitted from the circuit into the surrounding environment. The flow of electrons around the closed loop is called an electric current. The source of the electrons must be a chemical battery or a mechanical generator which produces a potential difference, also known as a voltage.
I am removing a dimmer switch to put in a regular switch but there are two incoming hot wires what do i do?
The regular switch just connects in the circuit the same way as the dimmer switch came out. If the dimmer switch had its own wires the only difference will be is you will have to supply your own wires from the new switch to the existing connection. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
What is an electrical isolator?
Something that doesn't let electricity throughAnswerAn isolator (UK terminology) or disconnector (US terminology) is a switch used to isolate a section of a circuit from any energised conductors, by presenting a visible break in the circuit. Isolators are not designed to break load currents (unless fitted with optional arc-breaking feature) or to break fault currents. In high-voltage systems, isolators are used in conjunction with circuit breakers -with the isolators opened after a circuit breaker has opened the circuit, and closed before the circuit breaker closes the circuit. For example, before one can perform maintenance work on, say, a high-voltage circuit breaker, the following sequence must be followed:the circuit breaker is opened, breaking the circuit.isolators located on either side of the circuit breaker are opened, presenting a visible break between the isolator and energised lines.temporary earth (ground) connections are applied to each side of the circuit breaker.barriers and warning signs are erected around the circuit breaker to define the permitted work area.a permit to work card, listing the work to be performed, and any potential hazards, is issued to the personnel who are to maintain the circuit breaker.
What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
How does a torch work-circuit?
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

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 materials will made an electric circuit work?
a dry cell a resistor (a bulb maybe) wire switch
Give two possible reasons why their circuit does not work when they close the switch?
The cell has no more electricity and the bulb has blown.
Where would you put an ammeter in a circuit?
in a series circuit or it will not work. Put it after the bulb
If you unscrew a light bulb slightly and leave the power on to it is it still using power?
Possibly. If it still works when you turn it on, the of course it is using power. If it does not work when it otherwise would, then it is definitely not using power, just as if you didn't have the bulb there at all. <<>> With the voltage on the circuit and the light bulb in the circuit, the bulb will glow. If you unscrew the bulb until it goes out the potential voltage will still be in the circuit but no current will flow so no power will be used. In this scenario the unscrewing of the bulb will be the same as using a switch in the circuit to interrupt the current flow.
What position does the switch have to be in for a circuit to work?
The switch would be open.
Why do the brake lights or tail lights not work if you change bulb and the fuses are good?
A bad brake light switch or a bad headlight switch, or the power source of the fuse has a problem or break in the wire (circuit).
What does a switch do in its circuit?
A switch allows the circuit to have a break in it therefor making it not work. It stops the flow of electrons.
If the filament of the bulb is broken would the circuit be complete?
If the bulb's filament is broken, the whole circuit becomes open. If the bulb is in a series circuit or is the only bulb, the electricity would no longer flow. If the bulb is in a parallel circuit, along with other bulbs, then only the blown bulb would go out, and the other bulbs would still work.
