How do you calculate inductance on an oscilloscope?
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. This is the amount of inductance of the device being tested.
What is difference between capacitance resistance and inductance?
Capacitance, as we now know, is the ability to store energy in the form of an electric field. Inductance, which is measured in henries and denoted by the letter L, is the ability to store energy in the form of a magnetic field.
How to measure capacitance and inductance using an oscilloscope?
The following two examples introduce capacitor/inductor/ ESR measurement using an oscilloscope and a function generator. For this application most oscilloscopes and function generators will give acceptable results since the test frequencies are below 100 kHz.
Can a function generator be used to measure inductive impedance?
An inductive impedance will have a current waveform that lags behind the voltage waveform. Fortunately, if you have an oscilloscope and a function generator in your lab, you can use a similar technique to make multi-frequency impedance measurements with good results.
How to find the inductance of a sine generator?
Put a series resistor with your inductor and try to read over the inductor. If the sine keeps the same, maybe your inductor has a low inductance. Try to lower the frequency of the sine generator
Can a function generator be used to measure capacitance?
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%-5% uncertainty.
