Power is closely related to Ohm's Law in resistance circuits and similar relationships apply. During everyday life we hear the word watt mentioned in reference to things like light bulbs and electric bills. Voltage is measured in volts (V) Current is measured in amps (A) Resistance is measured in ohms () Power is measured in watts (W) Electrical power, or the wattage of an electrical system, is always equal to the voltage multiplied by the current. The flow of current through a conductor is proportional directly to its voltage (I=V/R). Formula, Examples & Ohms Law | Electrical4U Watts Law: What is it? Formula, Examples & Watts Law Triangle What is Watts Law? Watts law defines the relationship between power, amperage, and voltage drop in an electrical circuit. Watts Law also states that the power of an electrical circuit is the product of its voltage and current. The values that can be calculated using Power Triangle are; Ohms law wheel includes another variable like power (P) which is calculated in Watts. I show how to use Watt's Law and how it works together with Ohms Law.
