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?
Ohm: Omega: O (after G. Ohm, 1787-1854) The derived SI unit of electric resistance, stated as the resistance among two points on a conductor whenever a constant potential difference of 1 V generates a current of 1 A in the conductor;
