If you don’t have an LCR meter in your lab or you want to demonstrate the behavior of capacitors and inductors under sinusoidal stimulus, an oscilloscope and a function generator can help you to do a simple, transparent impedance measurement. You can expect capacitance and inductance values with 3%–6% uncertainty.

17 Ιαν 2019 · Here both L and DCR are found by rating series C and self winding capacitance from the notch SRF at 1 MHz. Your mileage will vary. The 5K decouples potential Cin from output resonance with low gain high f NFB. Usually you want to test it in the frequency region it will be used.
The main difference between the inductive and the capacitive case is the phase 𝜑. In the inductive case, the phase is positive whereas the capacitive impedance has a negative phase.
Most labs have an ample supply of digital multimeters (DMMs) for measuring DC resistance, but when it comes to measuring inductance, capacitance and impedance, it is not always easy to find an LCR meter. lting current, both in terms of amplitude and phase relative to the AC voltage signa.
3 Δεκ 2018 · Set-up for measuring Inductance and Capacitance. Enough theory, now let’s get building the circuit on a breadboard. Here I have an inductor whose value I should find out by using a known value of inductor. The circuit set-up that I am using here is shown below
25 Οκτ 2021 · The LCR meter collects the difference and uses the difference between voltage current and phase to calculate the inductance resistance and capacitance of the component. The device operates by applying AC voltage on the device Under test.
