How does an open circuit occur?
An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.
How does a circuit breaker protect you?
A circuit breaker limits the amps that a circuit can carry. If the amperage draw on a circuit exceeds that limit, the circuit breaker turns off the circuit. If the current through a wire exceeds the rated amperage, the wire will overheat and eventually cause a fire, or at a minimum, destroy the wire behind inside the wall. Obviously, people don't want a house fire caused by an electrical overload, so circuit breakers are used to prevent damage and potential loss of life.
Why is a fuse important?
a fuse is important because if there is a overload of energy the fuse will take it in and if the fuse blows it means there is a problem or a thecnical problem with that source. a fuse can be found in a series circuit.
How are fuses or circuit breakers connected with other elements in the circuit?
Fuses are normally associated in series with the component(s) to be protected from over-current, so that when the fuse blows (opens) it's going to open the whole circuit and prevent cutting-edge through the ingredient
Why MCB are used instead of fuses?
MCBs are more convinient because when an excess current passes through it or a short ciruit occurs it just trips off and can be resetted after the fault has been solved, while the fuse just blows off(melts) when a fault occurs and it needs replacement everytime it operates.
What happpened when you give dc supply to ac devices?
Usually it blows the circuit-breaker and it might also ruin the appliance.
What devices shut down immediately if a short circuit occurs?
A circuit breaker shuts down and can be reset. (A fuse does not "shutdown", it fails, or blows, or breaks and cannot be reused.)
What happens if you over power an electrical circuit?
fuse blows, breaker trips, wire burns. if the latter is in your house, a smoke alarm is disireable.
Can the defroster in a 1994 GEO Prism cause the engine to shut down?
Do you mean the defroster fan? If so yes if it blows the main engine circuit breaker in the fuse block.
Give one advantage of using a circuit breaker rather than a wire or cartridge fuse?
An electrical breaker is dual function an electrical fuse just has one purpose.
What is the problem when a fuse blows on a 2001 Chrysler Town and Country?
A fuse blows when there is a short circuit or an overload in the circuit.
What one is better fuse or circuit breaker?
IMO it would be because the circuit breaker has the possibility of going bad and not working (allowing a short to move through the device), but fuses blow (cause a break) no matter what if shorted.
Does an air conditioner blow out heat or blow out cold air?
An air conditioner blows out heat
Does your home heating system use the air conditioner compressor for air flow?
No, the compressor only draws out the heat from air. The blower motor either blows warm air or cold air.
You have an elecwaterheater it blows the20amp in line breaker and the 50 amp main?
For a main breaker to trip under these circumstances the rest of the panel is becoming close to its load rating. When the 20 amps breaker trips the rest of the panel is close to or over 30 amps, the 20 amp breaker takes it over the top. What trips a HWT breaker is usually a faulty heating element. It could be the top one or the bottom one.
Why power circuits and lighting circuits require a separate circuit breaker?
Utility outlets and lighting outlets should be separate so that when a utilization device plugged into an outlet trips the breaker or blows the fuse, you won't be left trying to find your way to safety in the dark. Light fixtures are much less likely to trip a breaker in ordinary use, but there are places you also want more than one lighting circuit for illumination.
How does an open circuit occur?
An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.
