Current through resistors
How do I find out a maximum current flowing through a resistor with just the resistance of the resistor and it's power rating?
Watt: W (after J. Watt, 1736-1819): The derived SI unit of power, stated as a power of 1 J acting over the period of 1 s; it therefore has the units of J/s.
