Best Answer

it gets broken

A fuse is specifically designed so that when the current exceeds its specified rating, the fuse itself fails in some way (usually, part of it melts or burns out). When the fuse "blows", the circuit is cut open, so current can no longer flow.

A fuse contains a thin wire that melts when the current flowing through it exceeds a specific limit. Once the wire melts, it breaks the circuit and stops the current flow, protecting the circuit from damage.

What is the functions of a fuse?

The function of a fuse is to stop the current from flowing by opening the circuit when the circuit amperage exceeds the rating of the fuse.


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.


Fusing current capacity depend which factors?

Fusing currents is combining two or more wires together to join the currents. A critical factor is the temperature of the wire.


Will the convection currents stop flowing if the pot is no longer heated?

Yes, convection currents in a pot of liquid will eventually slow down and stop when the heat source is removed, leading to a decrease in temperature throughout the liquid.


What happens when an electric circuit is broken?

Then the current will stop flowing.


A break in the wires of an electric current will the circuit and the current?

A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.


If a pot is no longer heated when will the convection currents stop flowing?

Once the pot is no longer heated, the temperature of the liquid inside will begin to stabilize and the convection currents will gradually slow down and eventually stop as the temperature equalizes throughout the liquid.


What causes the horn to stop working in a 2003 ford Taurus?

A horn can stop working due to a faulty wire, fuse, or horn assembly. On a 2003 Ford Taurus check the wiring with a spark tester to ensure there is a live current flowing through.


When and magnetic fields exist its called an electromagnetic field?

A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.


What safety devices that stop the flow of electric currents?

Safety devices that stop the flow of electric currents include circuit breakers, which automatically cut off power when overcurrents occur, and ground fault circuit interrupters (GFCIs), which detect imbalances in current flow and shut off power to prevent electric shocks. Additionally, fuses are devices designed to disrupt the flow of electricity in the event of excessive current.


When does current stop flowing in a circuit?

Current flows in a circuit when there is a difference in electronic potential between two points.


What are the effects to the transformer insulation of single phasing on a three phase Delta-Wye connection?

The effect of the insulation is to stop electric currents flowing where they should not.
