WebbThis result should not be surprising since we showed (p. 33) that the power consumed by any resistor equals either of the following. v 2 R. or i 2 R (3) Since resistors are positive-valued, resistors always dissipate power. But where does a resistor’s power go? By Conversation of Power, the dissipated power must be absorbed somewhere. WebbIf the unit of power P = I × V and of voltage V = I · R is needed, look for "The Big Power Formulas": Calculations: power (watt), voltage, current, resistance. Some persons think that Georg Simon Ohm calculated the "specific resistance". Therefore they think that only the following can be the true ohm's law.
