It is simply a piece of wire. It's thin dimensions, limits the amount of current that can be sent through it before it melts.
If too much current passes through it, it will get hot. When it melts, it falls apart and breaks the circuit.
The thicker the fuse wire, the more current it will take before melting and the rating will be stamped on it.
For convenience, the fuse wire is normally contained inside a cartridge of some sort. Sometimes a glass tube with metal end caps, where you can see if the fuse wire is intact inside.
On modern car fuses, the wire is displayed across the top of a piece of coloured plastic with metal blades for connectors.
The current rating is stamped on the top and the color gives a ready indication of the Amperage rating.
What else can I help you with?
How does a fuse work to protect electrical circuits from overloading?
A fuse works by breaking the circuit when there is too much current flowing through it, which helps prevent damage to the electrical components from overheating or overloading.
Could the fuse on an Audi a4 cause the water pump to not work?
No, since it is not an electrical part.
Galaxy sharan wipers don't work?
Check your fuse and replace. If fuse and electrical connections are ok, then check the wiper linkages, they tend to sieze.
How does a fuse power a electrical plug?
A fuse doesn't 'power' an electrical plug. A fuse protects the load supplied by that plug.
Will an electrical fuse work correctly in a near-vacuum?
Yes, it will. In fact, it will work somewhat better at arc suppression because of the vacuum.
On a 1995 Toyota the power windows won't work. The dome lights won't work. The locks won't work?
Electrical, check the fuse box.
Your electrical outlets in 2004 dodge caravan se won't work they both start by ignition could it be a fuse?
The fuse would be the first place to check.
What energy does a fuse convert electrical energy?
A fuse converts electrical energy into thermal energy. When an excessive current passes through a fuse, it causes the fuse wire to heat up and melt, breaking the circuit and preventing damage to other components.
2002 pontiac sunfire At times They work just by turning them off and on and than at times I need to pull the fuse and put it back in or they work when the fuse is barely back in?
If the 2002 Pontiac Sunfire works at times and the fuse is causing trouble. There may be a short in the fuse box or electrical system.
What could be the cause if a popped fuse is found in an electrical circuit?
A popped fuse in an electrical circuit could be caused by an overload of electrical current or a short circuit.
How does a wire fuse work?
A wire fuse works by only allowing so much electricity to flow through. When the electrical current goes above a predetermined rate the fuse breaks and stops the electricity from doing damage.
How do you know when a fuse is blown and needs to be replaced?
When a fuse is blown and needs to be replaced, you can tell by checking if the metal strip inside the fuse is broken or melted. Additionally, the electrical device or circuit that the fuse is protecting may not work or may show signs of malfunction.
