The purpose of the fuse is to protect the equipment receiving power from overload or short circuit. Having no fuse could result in destroying the equipment and/or a fire.
In buildings the fuse protection (or circuit breakers) also protects the building wiring.
<><><>
While it is true enough that fuses are used to protect connected equipment and respond to direct faults, the size or rating of the fuse is determined, with limited exceptions, to protect the wiring system from damage caused by overheating due to imposition of currents higher than that for which the conductor insulation is rated.
<><><>
Your circuit is a chain of devices. This chain is only as strong as its weakest link. The rating in question here is current. When too much current is pulled through the chain, the weakest link gets hot. If this goes on too long, the weakest link may catch fire. If the weakest link is near flammable materials, it may catch them on fire.
Fuses or circuit breakers are designed to be, and must be, the weakest link in the chain. If too much current is drawn, the fuse burns open in a controlled environment as opposed to the wire in the wall. This also alerts the user to the problem, who can correct it and replace the fuse. (Or put a penny in it and watch the firetrucks.)

A circuit breaker is used in many homes instead of a?
Fuse
What will happen if a thick copper wire is used in fuse?
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
Can a 10 amp AGC fuse be used in a 10 amp rated DC circuit?
Yes, as long as the fuse is able to be inserted into the fuse holder it will work.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
A fuse or circuit breaker used in a circuit is usually inserted in?
A fuse or circuit breaker used in a circuit is usually inserted in series with the load.
What does ctsy-clk mean on fuse box?
It is a circuit fuse in a vehicle. The fuse is used to protect the courtesy/clock circuit.

What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
A fuse is used to protect a series circuit?
A fuse can protect the conductors in both a series and parallel circuit.
What will happen if a thick copper wire is used in fuse?
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
What is the used of the fuse in the power supply?
Fuse is used to protect against over load. The fuse blows off if there is overloading in the circuit. This prevents the flow of current in the circuit beyond the position of the fuse. The equipment which is overloaded in the circuit is thus saved.
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 size fuse for 12v battery?
The fuse you use is determined by the load on the circuit and the size wiring used in that circuit not the battery voltage.
What is the difference between 125V 15A fuse and 230V 15A fuse?
The voltage rating of a fuse (in this case 125V or 230V) defines the maximum circuit voltage that the fuse is safe to be used on. A fuse with a voltage rating of 125V should not be used in a circuit with a voltage greater than 125V. If a 125V fuse were installed in a 230V circuit and an overload current occurred, the fuse could explode.
What materials can be used to protect a circuit?
Fuse, screw in or plug, circuit breaker, fuseable link
What would happen if you used a 60 amp fuse in a 6 amp circuit?
On a fault condition of the circuit, the current most likely will not be removed. If this happens components in the circuit will most likely act as a fuse and will components will be completely destroyed. This is why the manufacturer recommends what size of fuse to use in their equipment and this fuse size should always be used.
