WebThe Planck constant is a fundamental physical constant. It is written as h. The Planck constant has dimensions of physical action: energy multiplied by time, or momentum … Claim: The Planck Constant can be used to derive Planck units (of time, mass, length, etc) which represent the smallest measurements of that type possible in the physical universe.
WebThe dimension of Planck’s constant is the product of energy multiplied by time, a quantity called action. Planck’s constant is often defined, therefore, as the elementary quantum of action. Its value in metre-kilogram-second units is defined as exactly 6.62607015 × 10 −34 joule second. Britannica Quiz.
