- Using an RCD is better than a fuse because it requires no replacement sacrificial metal strip. Also, more reliable and reacts more quickly to cut the circuit (can detect quickly since it is a more sensitive device).

A device that contains a thin strip of metal that will melt if there is too much current through it?

A fuse has a metal strip that melts and opens a circuit if the current becomes too great.


What thing protect equipment from too much current by tripping a switch that breaks the circuit stopping the flow of electricity?

In electrical terminology it is an over current device. This could be an electrical breaker. Another form of an over current device is a fuse.


What electrical safety device has a piece of metal that melts when a current becomes too strong?

A fuse is an electrical safety device that contains a piece of metal that melts when the current flowing through it becomes too strong. This melting of the metal breaks the circuit and prevents overheating of the electrical system.


Can you use a 15 amp fuse instead of a 10 amp fuse for your car gauges?

It is NEVER a good idea to use a higher value fuse. The reason for the 10 Amp fuse is that it blows at 10 amps which the wire and device being protected is designed to handle. If you substitute 15 amps and that amount of current flows in your device, it may destroy the device and other things in the path of the current.


Predict whether a fuse will work successfully if it is connected in parallel with the device it is supposed to protect?

A fuse will not work successfully if it is connected in parallel with the device it is supposed to protect.First, it will blow because it has no resistance in series with it. Second, once it blows, the device still has power applied to it. Fuses must be wired in series.

What is the term for fuse?

THis is the term. Fuse is a current sensing device that is set to open at a predetermined amount. Once current passing thru the device exceeds its rating it opens the circuit to protect the circuitry behind it.


How does a fuse help safety?

What fuse is the fuel pump fuse?

A fuse is an electric device that interrupts the flow of electric current when overloaded. The fuse pump will therefore perform the similar task.


An electrical device in the current path that melts or breaks when current exteeds a predetermined maximum value?

The device you are referring to is a fuse. It is designed to protect electrical circuits by breaking the circuit when the current exceeds a safe level, thus preventing damage to the device or overheating. Fuses can be easily replaced once they have blown.


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 do you measure amperage across fuse?

Technically, you don't measure amperage ACROSS a fuse, you measure current THROUGH a fuse, and the units of measure are amperage. If you want to measure the current though a fuse on a single device, say a TV, or computer, you can use a multi-meter. You will need to 'redirect' all the current so it goes through the multi-meter. ie: ----|fuse|---|device|--- would be rewired to be: ----|fuse|-----|black probe|---|multi-meter|---|red probe|-----|device|------ If you want to measure the current through a larger fuse, like the main fuse in your house, you'll need a current clamp. This is a clamp that you can put on ONE of the incoming power wires. It measures the magnetic field generated by the current. This is the much easier way since you don't have to do any re-wiring to redirect the current, but costs more money. ----|fuse|---@@---|device|--- [the @@ is the current clamp, note that it doesn't matter where the current clamp is placed, so long as it's only around ONE wire] Whatever you do, be careful, electricity is dangerous.


Will a fuse work successfully if it is connected in parallel with the device it's supposed to protect?

No, a fuse will not work successfully if it is connected in parallel with the device it is supposed to protect. Fuses are designed to be connected in series with the device, allowing them to interrupt the current flow when an overcurrent condition occurs. If connected in parallel, the fuse would not experience the same current as the device, and it would not protect it effectively from overcurrent situations.
