How is inductance measured
Web15 jul. 2024 · 3. Negative inductance is capacitance. The trick is interpreting it in your particular setup...if it's an inductor, you're past its resonance. The above looks like a capacitor that behaves as an inductor above its resonance (around 144.7 MHz). (For more fun, figure out what reverse resistance represents.) – Cristobol Polychronopolis. Web3 mei 2024 · One method, measuring inductance on a voltage-current slope, involves connecting the inductor to a pulsed voltage source with a duty cycle less than 50%. Using an oscilloscope’s current probe, read the peak current in amps and the time between pulses in microseconds. Multiply these amounts and divide the product by the peak current.
