  • Do you really understand AC impedance and DC impedance?

    Both DC internal resistance and AC internal resistance measurements have their own unique principles and operations. DC internal resistance is relatively simple to measure and is based primarily on Ohm's law. AC internal resistance, on the other hand, requires the injection and detection of a sine wave signal from which the corresponding impedance value is obtained.
