A: FUSES are very good for short circuit protection. On the other hand a short over current may not make the fuse to blow since it requires heat caused by the current to blow. There are fuses that are meant to blow fast and some fuses are designed to blow slow depending on the circuit requirement
What else can I help you with?
What do you understand about short circuit?
Not good.
What can prevent a short circuit?
Usually good workmanship goes a very long way to prevent short circuits.
How does good regulation affect the short-circuit current of an ac generator?
I assume by good regulation you mean a minimal voltage drop internal to the generator. Minimizing this will inherently increase the short circuit current, because it requires minimizing the internal impedance of the generator.
How to calculate the short circuit current of circuit breaker or cable?
A short circuit study is required for that, modeling the electrical system. The short circuit current is also directly dependent on the location of the building system relative to the power grid and type of transformer bringing power into the building. For starters and keeping it "basic" look for Cooper Bussman's Point to Point Method of Short-Circuit Calculation. That is a good start and depending on what you need a good start. Remember to contact the utility company for available fault current, type of voltage transformer, transformer impedance and size. If you want to get technical, get SKM's software (expensive though). With it you can go several steps further into short circuit analysis, selective coordination and finally arc-flash protection. Hope this helped. JP Ross, Professional Engineer
How did you check the electical resistance of the headlight earth connection?
Ohmeter connected both ends ground circuit. Usually this circuit very short with minimal resistance due to that. Do you have a good solid ground?
What type f circuit by passes most resistance and large dangerous curent flow?
A short circuit. In a properly installed system the fuse will blow to prevent a fire.
What is the best way to find a short in a 1997 GMC Suburban drivers side headlamp?
the better way to find and fix short circuit is replacing the blow fuse with any head bulb,while the short circuit is present the bulb becomes bright at high intensity , next step shake and wiggle wire harness and look for tiny spark against harness and ground ,when you discover the short circuit the bulb you connected as a fuse will turn off ,good luck
What is a good sentence for the word circuit?
circuit
How do you test for short to voltage?
The following procedure tests for a short to voltage in a circuit.1. Set the rotary dial of the DMM to the V(DC) position.2. Connect the positive lead of the DMM to 1 end of the circuit to be tested.3. Connect the negative lead of the DMM to a good ground.4. Turn ON the ignition and operate all accessories.5. If the voltage measured is greater than 1 volt there is a short to voltage in the circuit.
What would cause the turn signal fuse to keep blowing?
Could be there is a short to ground somewhere in the system or the circuit is overloaded with extras. If you have a trailer plug in back take a good look at that area for a short.
Can an iron nail replace a wire in a circuit?
An iron nail can replace a short length of wire in a circuit if the points of contact of the nail to the rest of the circuit have no rust or corrosion and good connection can be made. Using solder to join the nail to the circuit can help make a good connection. However, if this is for a scientifically controlled experiment fine as long as its very low voltage. If you are considering high voltage . DO NOT ATTEMPT IT. Its extremely dangerous
What is meant by the term short circuit?
When a wire is cut in a circuit, a gap is made and the current can no longer circulate, known as an open circuit.When 2 parts of a circuit touch, that shouldn't, for example - a wire comes loose and comes into contact with another part of the circuit, its shortening the route of the current in the circuit. So its a short circuit. When this happens 99.9% of the time the result will be a spike in amp's, so tripping any circuit protection, MCB's, fuses.A good example of a common short circuit is faulty windings on a 3-phase electric motor. If the resin separating the windings becomes damaged it can cause 2 or even 3 of the motors phases to come into contact causing the motors overload protection to trip.
