Negative ohms reading
WebMay 4, 2024 · "Internal Resistance" and "impedance" refers to the DC and AC characteristics. Internal resistance is traditionally measured by applying a load and reading the voltage drop, whereas impedance is obtained by applying a small high frequency AC signal (eg. 1KHz sine wave) and measuring its attenuation. WebTo measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter …
