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.

Fuses have a current rating marked somewhere on the fuse body. If this current is exceeded the fuse will blow.

Difference between overcurrent relay and fuse?

Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.


How does a fuse protect against a short circuit?

When too much current attempts to flow through a wire, the fuse will "pop." The metal conductor inside literally brakes into two pieces. At a specific amperage the fuse "pops", braking the circuit. At that point, there is no more current. So, the fuse prevents the current level from rising above a maximum amperage.


What is used to insure that too much current does not flow through one circuit?

A circuit breaker or a fuse is used to insure that too much current does not flow through one circuit.

What are the functions of switches and fuses?

A switch is a mechanical device for controlling the flow of current in a circuit, switching the current either on or off. A fuse is designed to melt safely when a current exceeding its maximum current rating passes through it, thus protecting the service wiring supplying power to the connected load. For example, if the connected load develops a fault which causes a high short-circuit current to flow in the service wires, if there's no fuse to break the flow of current then the service wires would get very hot and could cause a home fire.


What happen when a fuse wire of 100 ampere is used when a circuit at home draws a maximum current of 20 ampere?

The fuse or breaker should be no bigger than specified for the wiring and devices on the circuit. Your nominal current draw may be 20 amps, but a short circuit would cause maximum current to flow which in this case would be 100 amps until the fuse blew.


How does blown fuse in 2001 Toyota Tacoma pickup cause no CD player no radio?

The DC current has to flow through the fuse to reach the radio. blown fuse = no power.


Will maximum current flow through 0 ohms of resistance?

In theory, you would get infinite current. But, of course, in practise, this cannot happen, as any large current would cause severe damage to the source supplying that current, not to mention the conductors involved. Protection against such currents would be provided by a fuse or circuit breaker.


What is a fuse rating?

Fuses have two basic ratings. The first is current rating. The current rating is the amount of current that a fuse will safely pass before blowing. When the current flow through a fuse exceeds its rating, it opens up and breaks the circuit. If a fuse has a 5 A rating, it will open as current flow through it exceeds 5 amps. It is useful to note that there are some fuses that are designated as time delay. These fuses will sustain current in excess to their current rating for a short period before blowing. The fuse that blows immediately when its rated current is exceeded is an instantaneous fuse. The other way fuses are rated is by voltage. So when selecting a fuse, be sure that both the current and voltage rating are suitable for the application.Fuse rating is the permissible minimal current to pass in the fuse element,without causing the fuse to blow or melt.


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


Does the material used for a fuse wire need to have a low or a high melting point - a low or high ductility - a low or high resistivity?

The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor. As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.


What happens to a fuse when the flow of charges stop?

Current i.e.rate of flow of charge when stops flowing in a circuit then fuse does not blows out. The only work of fuse is to blow away when the current starts flowing greater in magnitude than the rated current value.
