When a circuit is inductive the current has what voltage?

This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.

When will a circuit breaker trip or turn off?

A circuit breaker has a specific amperage trip setting. That is the number on the handle of the breaker. When an amperage that is drawn by a load goes higher than the setting on the breaker, the breaker will trip off. This tripping action opens the circuit and drops off the load that was causing a higher than normal amperage.

What does a circuit breaker do for the safety of a house?

A circuit breaker sets a limit on the amount of amperage that can be applied to the circuit's conductor. This is why wires and breakers have amperage ratings. The wires ampacity is matched to the breakers ampacity. If there is a higher that normal amperage capacity, than what the wire is rated for, the breaker will trip the circuit open.

Is amperage rating and running amperage the same thing?

Usually the current rating for a circuit is higher than the current usually taken. This leaves a little margin for safety.

What size wire to use in a circuit?

Circuitry wire size is based on the amount of amps that the circuit is to draw. The higher the amperage the larger the wire size has to be.

Will a circuit breaker give off less amperage?

A circuit breaker does not give off amperage. A circuit breaker allows a flow of current up to the rating of the breaker. Any current higher than that of the breaker's rating will open the breaker's contacts and stop the flow of current.

Does temperature change when changing the longitude?

Yes it does change the higher you get

Will a fuse of a higher amperage rating have a higher melting point link?

No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.

Can a 8 amp be changed to 15 amps on circuit breaker?

If you are asking if you can change an 8 Amp Circuit Breaker to 15 Amps, the answer is no. If there is an 8 A breaker in place it is sized to protect the wiring and devices on the circuit. Increasing to 15 A would defeat this protection and could cause a fire or cause a connected device to be destroyed with higher amperage.

It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?

It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?

Why is it not okay to use a fuse with a higher amperage rating in an electrical circuit?

The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed by this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.

Can you run a motor of greater amperage draw with a motor of less amperage draw?

It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.

Can you add another appliance to a circuit by simply changing breaker to a larger amperage?

The most sensible solution is to get a qualified electrician to check the wiring to see what the maximum load should be, and if necessary re-wire with higher capacity wire/configuration. You can (there is nothing physically to stop you), but whether it is a good idea or not is a totally different matter - you risk starting a fire if you do. The breaker amperage is set based on the wiring of the circuit - the wire used, along with how the wiring has been done, will limit the maximum current that can be allowed through the circuit; if this maximum is exceeded there is a risk of the wiring overheating and causing a fire.

What happens to amps when you increase the resistance of a circuit?

If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).

Does using a higher than necessary ampacity in electrical circuits cause a higher electrical meter reading?

No, the electrical meter reads watts by multiplying the voltage and the amperage used in electrical circuits. Using oversize wire does not govern the amperage flow to the load. The load resistance in the circuit is what governs the amount of current that flows through the wire. This current in the load circuit is multiplied by the voltage applied to the circuit at the electrical meter. The product of this multiplication is wattage, multiplied by the amount of time the load is on, is what the electrical utility bill is based on.

How is a series circuit different from a parallel circuit?

A series circuit is connected + to - to + to - and so on and you end up adding the voltages of the power source Like in a bank of torch battery's. In a parallel connection you connect the + positives together and The - negatives together and end up with the same voltage but higher amperage.

How do you measure voltage resistance and amperage in a circuit?

With an instrument called a multimeter. The single meter incorporates within it a volt meter, an ohm meter and an amp meter. For higher amperages a clamp on amp meter is recommended as the circuit does not have to be opened to take a reading.

Can you plug a motion detector light into an outlet?

Yes of course, power is power, all 110volt, what ever the source in your house (except a dryer circuit that is usually higher). The difference is the amperage of the circuit. Lighting circuits have amperage controlling breakers that are usually 15amp, power circuits are usually 20amp but excepting a very very unusual condition you would not need to worry about it.

Horn fuse 1986 k-car?

The fuse in a circuit is designed to protect the wiring first and foremost. If there is a fault in the horn or other parts of the circuit, that causes a short circuit, then it could melt the wire and cause damage to other components or even a fire. The idea would be that the fuse would blow instead. If you take a look at the size of the wiring you will find several websites that will tell you the maximum amperage the wire can take. The actual amperage required to run a diaphragm horn is quite low, less than 5 amps at 12V. If you have air horns the start up amperage of the compressor can be much higher. You might find that there are other ancilleries running off the same supply though, so the fuse amperage needs to be less than the cable can take but high enough for the sum amperage of the ancilleries on the circuit.

Where is the Circuit breaker located on 2000 Ford Windstar and how do you test it to see if it needs replacing?

There are many "circuit breakers" got to be more specific. There is a fuse box inside the van and another higher amperage fuses in the power distribution box in the engine compartment.

Why does a wall switch 'crackle' and the light flicker?

There is a high current draw on the circuit and the switch is getting old. Change out the switch, see if you can find a 20 amp switch as the internal contacts are designed to take the higher amperage. Check how many lamps are in the circuit in watts, add them together and use the formula for amps. Amps = Watts/Volts (120).

How do you calculate the size of cable according to current?

First determine the amperage of the circuit . e. g 15 amp or 20 amp ( typical household circuit ratings) the gauge is 14 and 12 respectively. The lower the gauge number the higher the current handling capability.

Is a 10 ampere fuse suitable for 240 volt?

Yes a 10 amp fuse can be used to protect a 240 volt circuit. The amperage rating of a fuse is based on the given amperage load of the circuit. The voltage rating on a fuse must match or be higher than the voltage that is applied to the fuse. In other words you can not use a 240 volt fuse on a 277, 347, 480 or 600 volt circuit but it can be used on a 120 volt, Manufactures of switching equipment today make it impossible to interchange different voltage fuses to be installed in higher voltage switches.

Can you replace a 15 amp with a 25 amp fuse?

No. By using a higher amperage fuse, you allow more dangerous current to pass through the wires. The fuse would not be able to do its job: protecting the circuit.

What happens if you put a 100w bulb in a 75w lamp?

It draws more current (amperage) because higher rated bulbs have less resistance in them. The lamp device is designed to contain a certain amperage. If you use higher wattage bulbs its causes the amperage in bulb to exceed that of the lamp it is put in so if left on long enough it will either (1) Burn up the lamp and possibly cause a fire if left on long enough and or (2) overload the circuit breaker and trip it off.
