WebApr 2, 2024 · A Basic Circuit Example of Transmission Line Reflection Coefficient. A 12-volt source connects to a 24 Ω load via a cable with a 50 Ω characteristic impedance (Z 0 ). A short time later, 12 volts arrive at the load accompanied by a current of 240 mA (12 volts 50 Ω). But, because the load is 24 Ω, there is a potential violation of Ohm ... WebFor example, Staverman's coefficient is equal to zero when the solute can diffuse through the membrane as easily as through pure solvent (no membrane resistance), κ α D α = D 0 α. Conversely, if the solute cannot diffuse through the membrane, κ αDα = 0, which leads to σ α = 1 and Pα = 0. Substituting Eqs.
