In wirewound resistors, another selection factor is the temperature characteristic of the wire. The resistance of all materials changes as their temperature changes. If the temperature is lowered, resistance (typically) declines. In fact, if cooled sufficiently, the...

What is a surge resistor? A surge resistor is a resistor installed in a circuit to prevent a “surge” when conditions arise where a surge might occur. There are a number instances where energizing a circuit is followed by a surge of current. Like almost all...
