Answer:
In other words the maximum current allowed is the square root of the ratio between the resistor's power rating and worst case resistance. So for example if we have a 1k ¼Watt 5% tolerance resistor then the maximum resistance in tolerance would be 1050 and so the maximum current is: which is 15mA.
