The aluminum alloy resistor is a current-limiting element that is connected in series with a resistor in the circuit and can be constrained by the magnitude of its even branched current. If a resistor is near zero ohms, the resistor's current will not prevent the series circuit's affected resistors from being shorted and the current is infinite.
Wirewound resistors are generally used as high current limiting resistors that are not available. When the cylindrical wire is wound around the resistance and some of the skin that will be black or burns looks cracked, cracks, and some do not trace. Cement is a resistance wire wound resistor and may crack when burned, otherwise there is no visible trace. When burning some resistance and the appearance of a safe piece of skin will blow up, there is no trace, but black has never burnt.
Resistance is the maximum number of parts for electrical equipment, but it does not have the highest failure rate of parts. The most common damage, open resistance, resistance becomes larger than the rare, very rare resistance becomes smaller. Common carbon film resistors, metal film resistors, wirewound resistors and resistors are several safe. The second most widely used resistor case, the higher the damage first, the lower the resistance of the low-resistance characteristic and the higher the resistance, the central resistance; secondly, when the damage is often low-resistance charred black, very simple The discovery, and there is evidence of damaged high resistance resistors.
If a resistor with one or more large or infinity resistors with this resistance is connected in series with a resistor, it can be considered as an open circuit and the current is zero. Between the resistors used between the two extremes commonly used in industry, it has a certain resistance current through unavoidable, but not so great when short-circuit current. The effect of the restriction is similar to that of the large diameter of the connected water flow and the resistance between the two small diameter tubes.
