Explanation:
Detailed explanation-1: -The SI unit of power is the watt (W), which indicates the rate of 1joule of work per 1 second. Power is then directly proportional to the work done and inversely proportional to the time to do the work.
Detailed explanation-2: -Complete answer: By Ohm’s Law, if resistance (R) and temperature remain constant, then current (I) is directly proportional to the voltage (V). As per the power formula, if the power stays the same then current is inversely proportional to the voltage.
Detailed explanation-3: -As a result, Resistance is inversely proportional to Power (R).
