What is an object called that melts under high voltage to protect circuits?
A device that melts under high current , not high voltage is a circuit protective fuse. There are many fuses that are rated for voltages in the 10,000 volt range. It is the over current that trips them.
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.
The first measure you should take to help prevent damage against electrical problems is to do what to the circuit?
Protect the circuit with an OCPD, an over current protection device, such as a circuit breaker or fuse.
How do fuses protect wires from overheating?
The fuses restrict the amperage (electrical current/flow) of the circuit. The fuse is size according to wire size and load requirements. NEVER put in an over-sized fuse as it will allow to much amperage for the circuit which will cause overheating of the circuit and possible fire.
What do fuses and circuit breakers do?
Fuses and circuit breakers protect the conductors that are connected to them from not letting the current going above the current rating that is given to individual size conductors.the main function is to quickly stop the power to continue threw the loop., and to protect ,equipment from damage and people from dying, that may be in contact to a shorted circuitCommentFuses and circuit breakers are overload protection devices, designed to protect loads (e.g. appliances) against overload or short-circuit currents. They are not designed to protect people.to over come the over load conditions.In simple terms the purpose of a fuse or circuit breaker is to protect the wiring from overheating and causing a fire. That is why it is so very important to match the fuse or breaker with the size wire in the circuit.Protect the circuit from over current. Fuses and breakers prevent excessive amounts of current to flow through the conductors in a circuit which causes heat to build up making for a fire hazard.A circuit breaker or fuse is a protective device that shuts off power when the current exceeds a preset limit. It is designed to protect the wiring, and thus prevent damage to the equipment and fire.
What is used in an electrical circuit to prevent a short current?
A Fuse or a circuit breaker can be used to protect an electric circuit from over loads. A surge arrestor / over voltage relay can be provided for voltage protection An ELCB/ Earth fault Relay may be provided for earth fault protection. Electrix Chennai, India.
Is a fuse a device that keeps electrical circuits from over heating?
A fuse is a device used to keep electrical circuits from overheating is not a true statement. A fuse is used to protect the wire of the circuit from an over current being applied to the circuit. This over current could be caused by a couple of scenarios. Two non insulated conductors touching one another and creating a short circuit. Another cause could be an non insulated conductor touching adjacent grounded equipment. Whatever the cause the fuse will isolate the fault instantaneously.

Can a 3.15A 250v fuse be replaced with a 5A 250v fuse?
NO! The circuit wiring is protected by that 3.15 amp fuse. Put a 5 amp fuse in the circuit and the wiring may overheat and cause a fire. Never over-fuse any circuit even in an emergency.
What is a brown fuse and why should you never replace one with a penny?
I believe the question should be what is a BLOWN fuse and why should you never replace it with a penny? A blown fuse would be one that has been over stressed and has burnt out or blown out to protect the wiring or other part of the circuit. A penny would bypass the fuse which is the safety measure in the circuit. Bypassing a fuse could cause a fire or serious damage to the device.
What is the maximum current that can flow through a fuse?
A current rating of a fuse is designed to open a circuit at a specific current flow. This rating is imprinted on the fuse and lets you know what the maximum amount of current the fuse is designed to open at. A fuse is in the circuit to protect the conductor that the current flows through. Never over fuse a conductor's current carrying capacity.
