Ohmâs Law / Wattâs Law Description and practical example: Ohmâs Law states the relationship between voltage, current and resistance. Given the relationship. between these three elements, once you know any two of them, it is possible to calculate the third. Wattâs Law is similarly useful in figuring out the relationship between power, voltage and current.
