WebJun 13, 2015 · The key thing here is if the supply survives and the voltage has dropped, then there is less voltage across the resistor which means there will be less current required to satisfy Ohms law - now this all happens in a very quick transient, so essentially all you see is a 5Ohm resistor with a very low voltage across it. WebV = I × R. and the Power Equation. P = I × V. A simple use of these is finding the power rating required for resistors. In this case, enter any two of the following values: the voltage across the resistor, the current through the resistor, or its resistance in ohms to find the power dissipation in watts. This is the minimum power rating you ...
