Impedance matching ratio

Witryna31 lip 2024 · Impedance matching In electrical engineering, impedance is the ratio of voltage to current with the consideration of phase angle. According to Ohm’s law V= … WitrynaIt can be defined as "the ratio of reflected voltage to the incident voltage at the load terminals". $$\rho = \frac{reflected\:voltage}{incident\:voltage} = \frac{V_r}{V_i} \: at \: load \: terminals$$ If the impedance between the device and the transmission line don't match with each other, then the energy gets reflected.
