Is a circuit Protection device made from special metals that shut off a switch if too much current flows through a circuit and there is a risk of overloading or overheating the circuit?
The (only) protection device which works like that is a fuse. It is simply a short length of metal which melts when too much current flows through it.
What electrical safety device has a piece of metal that melts when a current becomes too strong?
A fuse.
What is a liquid metal conducts electricity and does not change when a current passes through it?
This metal is mercury.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Which metal contains cholorophil?
Chlorophyll contains the metal magnesium.

Does current pass through a currency coin?
Yes, coins are made of metal and metal will carry an electrical current.

How can you test if something is a metal?
Run an electrical current through it :)
Why can't we use a strip of metal in place of fuse?
A fuse is a safety device, and the connective wire inside it is specifically designed to melt if the current exceeds a safe level. Once the wire breaks, the circuit is broken, preventing damage to the device in question. If a blown fuse is replaced by a strip of metal, the device 'works' but this safety feature is lost. If there is a power surge, the device is no longer protected because the current will continue to flow through it until its own components overheat and melt, possibly causing a fire.
How do simple metal fuses work?
Quite simply, a fuse limits the current which can flow through a circuit. If a device contains a 13A fuse, then the metal will melt when a current of 13A (to within a specified error) flows through it. When the metal has melted, the circuit is broken and so no current flows. The metal is encased in an inert gas or vacuum, to prevent decay over time and burning under high currents, which would be less predictible than melting. Different types and thicknesses of wire vary the fuse's current rating. In many applications, fuses have been superceeded by various types of sure-arrester and trip-switch, which are usually resetable (do not require replacement) and may act faster, more reliably, in diferent ambient temperatures or be remotely monitored etc...
How an electric current is produced?
When charges (means charged bodies) move , then we say that an electric current is produced. If charges remain at rest, current is zero. If charge Q moves through a metal in time t , then current I through metal is: I=Q/t; moreever, electric current can also be produced by rate of change of magnetic field through a metal...,
How does a electric current flow through a light bulb?
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
When dangerously high current flows through a thin strip of metal it melts and creates an open circuit and current stops flowing?
It's OK as a statement so the question mark can be deleted. <<>> This type of device is known as a fuse and it is the fuse's link that melts open.
