The fuse is called a fuse from the low -pimion alloy wire of the resistivity comparison of the resistivity. The more the voltage fixed resistance can detect the super -operating range of the micro -current resistance, the more current, which can be fused to burn the electrical appliance without melting. Some principles use current thermal effects fuses to control the flow of current to allow current flow to be allowed according to the formula Q = IRT resistance production is more calorie and easy to disconnect and safely to protect the protection. It has a certain relationship with the law of Jiao Er It is not small, and it is easy to burn the wires in the family and even cause fire. If it is small, it is easy to melt and cause unnecessary trouble.
The fuse can directly look at the principle of wires. Simple rated current internal waiting fuse is indeed the same as the wire. The temperature is higher than the same voltage of the wire with the cross -sectional area, the current fuse voltage, the current is lower than the wire ignore the voltage conditions, and the current is only 2.3%of the fuse tolerated current. 20maho fuses are in the wire of the wire pusher parallel light bulb: The current is lower than the fuse rated current light bulb with only weak voltage, current (similar to short -circuit) current super fidge -filaments rated current light bubble bright fuse burn.
