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.
What is a device that contains a thin strip of metal that melts if there is too much current though it?
A device that contains a thin strip of metal that melts when there is too much current is called a fuse. It serves as a safety mechanism in electrical circuits, preventing excessive current from damaging devices or causing fires. When the current exceeds a certain threshold, the metal strip heats up and melts, breaking the circuit and stopping the flow of electricity. This protects the system by ensuring that the current remains within safe limits.
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.
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?
Yes, a circuit protection device such as a fuse or circuit breaker is made from materials that can quickly interrupt the flow of current if it exceeds a safe level. This helps prevent damage to the circuit or connected devices due to overloading or overheating.

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

This metal is mercury.
How can you test if something is a metal?
Run an electrical current through it :)
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.
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.
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.
