Suppose if I want to purchase the 15 milli Ohm resistor , when I am thinking about the Power Dissipation.
In my circuit,
Max expected current is 5A and maximum possible power dissipation,
Pd = ILoad (max)^2 * Rsh = 5A * 5A * 15 mOhm = 375 mW
Does it mean that the resistor I choose that should be more than 375mW ?
Because, Can I choose if the resistor 15mohm with 1W and 1% . In this case, should I consider this resistor or Can I use this resistor for my circuit with above given requirements?
