What is the latest technology in circuit breaker?
The latest technology used in circuit breakers are Arc Fault Circuit Interrupters. They will shut off the circuit if the hot and neutral or two hots touch.
How does a circuit breaker help protect against short circuits and circuit overloads?
Quite simply, so you don't put too much current on the wires than they can handle. They also provide protection from 'ground faults', which is when the 'hot' and neutral wires touch. This causes a spike of current (because the resistance drops to near zero) and the breaker senses that too, or it should when it functions properly.
What is meant by the term short circuit?
When a wire is cut in a circuit, a gap is made and the current can no longer circulate, known as an open circuit.When 2 parts of a circuit touch, that shouldn't, for example - a wire comes loose and comes into contact with another part of the circuit, its shortening the route of the current in the circuit. So its a short circuit. When this happens 99.9% of the time the result will be a spike in amp's, so tripping any circuit protection, MCB's, fuses.A good example of a common short circuit is faulty windings on a 3-phase electric motor. If the resin separating the windings becomes damaged it can cause 2 or even 3 of the motors phases to come into contact causing the motors overload protection to trip.
Is a short circuit dangerous?
A short circuit is simply a circuit in which the resistance is substantially low. This means that the current of electrons flows far too fast and overheats. This can also form electric arcs (electrons jumping from one point to another). Three common results of short circuits can be: overheating (causing fires), overheating (causing explosions), and electric arcs (causing electric shock).
What happens if phase wire touch to earthing?
When a phase line touches the neutral by any conducting material means the Short Circuit. If there is a short circuit then the current in that circuit will be much higher and this increase in current may damage the the devices that are connected to that line.
Does the winding of voice coil need to varnish?
It can be bare (without varnish) but they should not touch each other as this will create a short circuit.
When two conductors leading from the power source touch medal to medal this is called a what circuit?
Short Circuit
What may happen when two live wires touch each others?
short circuit
Is it true that if you play with your iPod touch while it is charging there is a chance the batter will short circuit?
no it will not i do it all the time
What is it called when wires connect accidentally?
If two ungrounded (hot) conductors touch or an ungrounded and a grounded (neutral) conductor accidentally touch, it is called a short or short circuit. If an ungrounded or a grounded conductor touch an equipment grounding conductor, it is called a ground fault.
What best describes the condition that occurs when bare wires in an electrical circuit accidentally touch causing more current to flow than the circuit can safely carry it will cause a fuse or circiut?
The correct name is a Short Circuit.
Which circuit fault occurs when previously unconnected conductors touch one another allowing current to bypass part or all of a circuit?
If the word unconnected was changed to uninsulated then this type of scenario would be known as a short circuit.
What happpens when the anode and cathode touch?
A short circuit occurs. Depending on the potential sparks, fire and other bad things may happen.
What happens if neutral and hot wire touch on the same pole of a light switch?
You will get a short circuit and breaker will trip. If they are tied together on the load side of the switch the short will happen when you turn the switch on.
Why should the grounding wire of the appliances be inserted to the ground?
in case there is a short circuit of the appliance motor. if the ground is not plugged in, the metal housing of the appliance could become electrified and the first time you touch it you become the grounding source and could be electricuted!
What is a grounded circuit?
When wires are not insulated,not even a single fiber of it should touch or connect to the metal base or part of the project because it will result to a grounded circuit
What causes a short circuti?
An electrical short circuit is when two bare wires touch each other. Or when one wire's insulation wears too thin and the bared wire touches the metal chassis of the device and is led to earth.
