Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.

Why would your lights and horn not shut off?

Have you checked for a relay that might have been damaged when the fuse blew? With an overcurrent, it is possible for the relay to pick up and then become 'welded' so it will not release. If you find the relay and remove the cover, the contacter should move when you apply a little pressure to it. If this doesn't happen, replace the relay. Much harder to check would be if insulation melted during the overcurrent and fused power to a horn and light wire. Relay for sure.

What is the difference between reverse current and overcurrent protection?

A reverse current relay senses Power in (uses both voltage and current, and looks at the phase angle between these), and operates if power is flowing in the reverse direction, and the current is above a set point. An overcurrent relay looks at only current, and operates if it is above a set point regardless of power flow direction. Reverse current relays are often referred to as reverse power relays.


The fuse between 12V car battery and relay for 2x 100w spotlights keeps blowing?

obviously you need a bigger fuse and a bigger relay


A fuse has low melting point why?

This is necessary because a fuse is a protection against an overcurrent; excessive current produce melting.


Fuel relay fuse?

can a fuel relay fuse make car not start? If the fuse or the relay is bad, yes.


Fuse keeps blowing when replaced?

There is an overcurrent situation in the circuit, could be a wire shorted to ground.


Can a fuse be used to store and electrical charge?

No.A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.


Where is the ac fuse between the fuse box and ac relay on a 77 Chevrolet Malibu Classic under dash or the hood?

There is a fuse for the air conditioner and one for the fan. You have a power source to the fuse. From the fuse the relay gets it's power and then the fan and or the air conditioner compressor.
