WebIn the balance the force is the weight of a mass standard. Electrical power can be measured as a product of two frequencies and the Planck constant. These have to do with two quantum mechanical effects that are being used to measure voltage and resistance. Hence, the unit of mass can be linked to the Planck constant." WebThe energy E of each quantum, or each photon, equals Planck's constant h times the radiation frequency symbolized by the Greek letter nµ, ν, or simply E = hν. E = hν. E - the energy of each quantum (the energy of a photon) h - Planck's constant - 6.6262 x 10⁻³² J⋅s. ν - the radiation frequency.
