Which electric safety device easily melts whe there is overheating or overloading in the circuit?
fuse?
What happens when you connect live wire to ground?
This is a short circuit which will create sparks. The breaker or fuse on the circuit will likely trip or blow.
Why should you always switch off a circuit before replacing a fuse?
Main reason is for safety. Another reason is because if there is a heavy load, you may blow the fuse.
Why are there fuses in plugs?
They protect the rest of the circuit when the current goes to high, usually, because of a short circuitshort circuit means a very low resistance is connecting the source terminalsthen according to ohm's law,Current = Voltage / ResistanceI = V/Ras R -> 0I -> Infinityassuming a fuse of 10A, when a short circuit occur, the current starts getting highonce it passes the 10A limit of the fuse, the circuit gets disconnected from the sourceA Fuse is an electrical element used in electrical circuits to give protection to the systems against high current flow.It prevents the hazardious conditions as a safety device.
What safety devices that stop the flow of electric currents?
There are two types. A fuse is a piece of wire that is thinner than the circuit it is placed in series with. Any excessive current causes the fuse to melt and this cuts off the power. The fusing current is somewhat unpredictable. A circuit-breaker is a resettable device that can be set to interrupt the supply at a fixed amount of current.
What will happen to a safety device if there is short circiut?
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
Why the fuse wire necessary in a circuit?
It is a safety device. It is not an essential part of the circuit.
How does a fuse help safety?
A fuse is a safety device that helps prevent excess current flowing in an electric circuit.
What is the purpose of connecting fuse in both positive and negative terminals?
Because if it is not connected to both it is not a full circuit and therefore if it is not a full circuit then the fuse can't protect you.
What device protects an electrical circuit?
An example of a circuit protection device is a fuse. Another example is a circuit breaker.
What happens when a fuse blows?
When a fuse blows, it essentialy breaks the circuit. So the current can no longer flow, this is used as a safety measure.
What is the safety feature in preventing overheating of wiring?
A circuit breaker, or a fuse.
Can you connect a 15A 120V circuit to one phase of a 240V stove circuit without overloading the stove circuit?
Short answer: probably not. Longer answer: It depends on the size of wire feeding the stove, the stove amperage, and what you intend to connect to the new 15A circuit. If you just want to wire a light for the garage, sure go ahead. If you want to install a receptacle for a microwave oven, no way. Make sure you put a fuse to protect the circuit you are connecting.
If we connect Fuse wire to neutral how will it affect safety?
prepare to fry
Used as a form of safety device in a circuit give one word answer?
A fuse or circuit breaker will fit this description.
What is an analogous safety device in an electric circuit corresponding a shear pin in a mechanical system?
A fuse or circuit breaker
