WebImpedance is calculated by dividing the voltage in such a circuit by its current. In short, impedance can be described as limiting the flow of current in an AC circuit. Impedance is indicated by the symbol “Z” and measured in ohms (Ω), the same unit used to measure DC resistance. How do you measure speaker impedance with a multimeter? WebA common objective measure used to assess device and electrode function is impedance (a measure of the resistance to current flow). Impedance measures are affected by the electrode-tissue interface, resistivity in the fluid/tissue medium, and resistivity of the electrode contact and lead wires . It is not uncommon to encounter impedance ...
