How a circuit breaker prevent from too much current flowing into device?
The current (in question) flows through both the circuit AND the circuit breaker [they are in series]. Within the circuit breaker when the current exceeds the preset limit it will open the circuit thus stopping all current flow. There are two common ways of doing this 1) magnetism - a coil pulls a switch open 2) thermal - a bimetallic strip bends away from its contacts, which opens the circuit.
How do you reset an electric outlet after electricity went off?
You may have to locate the fuse box or circuit breaker box and reset or replace whats needed. Most outlets dont need to be reset unless they have little buttons on them, meaning it is a GFCI outlet - in which case it will have a little button that says reset on it.
The electrical Breaker will not reset?
To reset a breaker move the handle completely to the off position. If it had tripped you will feel a little resistance as it goes to the off position. If this doesn't restore the power the breaker is either bad and in need of replacement, or there is a persistent fault in the circuit causing the breaker to immediately re-trip. Breakers are safety devices.
What can cause a circuit breaker to suddenly start tripping?
If the breaker trips when nothing is turned on it could be a mouse problem. If it only trips when certain lights or appliances are turned on one of them is probably the reason.If it trips when nothing is being turned on or off something is getting hot. You should then have qualified electrician look at it. Hope this is usefull.
Why is the power off on on breaker when it is not flipped off?
Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.

Why is it important that homes have circuit breakers?
Fuses and circuit breakers are meant to protect your home's wiring from the heat generated from fault-currents and over-currents. Over-currents happen when you exceed the amperage the fuse or breaker is rated for over a period of time (IE: drawing 20 amps on a 15 amp circuit breaker). When this occurs a fuse or circuit breaker will open the circuit so the wiring in your home will not be damaged. Over-currents happen when electricity finds a path, other than the one intended, to ground. When this happens there is very little resistance to slow the flow of electricity and the amperage through the circuit can exceed the fuse or circuit breakers rated capacity by several hundred times . These type of faults cause the fuse or circuit breaker to open the circuit very quickly.
Where is the circut breaker?
Circuit breaker. The circuit breaker should be near the pedals next to the door. It also depends on what kind of car that you have. But usually they are near the pedals by the door. They should be under the dashboard, in a little box. The instructions for them is either givin to you when you buy the car, or they are on the panel door for the circuits and stuff.

Your 1999 Mercury Mountaineer headlights keep randomly shutting on and off you have checked fuses what could be the cause?
Ok it was the "turn signal" or "multi-switch" the switch that controls wipers,turn signal,brights and dims ect. it was pretty easy to replace and was about $60.00.AnswerDoes it have automatic headlights? If so, it may be the sensor. It could also be a circuit breaker. Many headlight circuits do not use a fuse, instead they use a circuit breaker so that you won't get stranded without headlights. If it's a circuit breaker problem, you may have lights that are drawing too much current for the breaker, on the other hand, it could also be a faulty breaker... assuming that you have a circuit breaker in that vehicle. You may need to do a little research, either at your local library or at the dealership. Sometimes a dealer mechanic will give you a little information so that you can perform some of the more simple repairs yourself.

Where is the circuit breaker on a ford 1970 thunderbird?
On the passenger's side, duck down under the glove box and use a light to look up into the dash. There should a few vaccuum hoses and wire harnesses as well. Beyond that there is a little box with 2 nuts that has 2 bolts coming out of it. That is your circuit breaker panel.
How does a fuse or a circuit breaker open a circuit?
In a fuse the conductor, or little piece of wire you see inside the fuse is designed to designate when it heats up above a certain level -- if the current climbs too high, it burns up the wire. Destroying the fuse opens the circuit before the excess current can damage the building wiring. Once a fuse blows it must be replaced with a new one of the same amp rating. The basic circuit breaker consists of a simple switch, connected to either a bimetallic strip or an electromagnet. The hot wire in the circuit connects to the two ends of the switch. When the switch is flipped to the on position, electricity can flow from the bottom terminal, through the electromagnet, up to the moving contact, across to the stationary contact and out to the upper terminal. The electricity magnetizes the electromagnet. Increasing current boosts the electromagnet's magnetic force, and decreasing current lowers the magnetism. When the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage. The entire linkage shifts, tilting the moving contact away from the stationary contact to break the circuit. The electricity shuts off. Resetting the breaker allows current to flow again. Fuses and breakers are there to protect the wiring and not what is plugged into the circuit.

What is the effect of a short circuit on other devices in the circuit?
Electricity is designed to complete a circuit. For example, it comes into your house by way of the hot wire. Then it goes through the electrical box and through the fuse system. Finally it goes through a light bulb or some other electrical devise. Then it goes back through the neutral wire. It wants to get back to the neutral wire without doing any work. In a way, electricity acts like a river. A little stream leaves the river to run your lightbulb. However, every now and then, there is a short circuit. The circuit leading to the light bulb develops a short circuit. In that case, a lot more electricity than should tries to go through the little wire that led to the light bulb. It wants to get to the neutral wire. It is like a river overflowing through a little stream and creating a flood. It can burn out the little wire and set the house on fire. The flood runs into a culvert which holds back the flood. The short circuit blows a fuse or throws a circuit breaker and the house does not burn down. Every now and then the main fuse box blows out and a house burns down. Every now and then a wire falls down outside and people walk close to it. The ground is full of electricity and the people are killed. So a short circuit happens when electricity completes a circuit without doing any work. It is dangerious when a fuse does not blow.
What circuit breaker acts as a switch creating an circuit when current is too high?
No. circuit breakers are in series with whatever lines they are protecting. They are never put in parallel with the protected loads (this would defeat the purpose). Circuit breakers open resulting in an open circuit / no power to outlets when they trip.
