How To Measure The Inductance Of Inductor

Another method for measuring inductance using an oscilloscope involves connecting a resistor of known value in series with the inductor under test and applying a signal. Stimulate the circuit with a function generator and view the junction between the resistor and inductor on the scope.

How To Measure Inductor Maximum Current Electrical

The basic unit of measurement for inductance is called the henry h after joseph henry but it also has the units of webers per ampere 1 h 1 wba.

How to measure the inductance of inductor. Adjust the frequency of the generator to approximately 20 khz. Then you can set up the current monitors and begin your measure. If you have neither a more indirect way is to use an oscilloscope.

Multiply these amounts and divide the product by the peak current. To measure inductance on a voltage current slope connect the inductor coil to a pulsed voltage source and keep the pulse below 50 percent. Adjust the output voltage of the generator to 1 v peak peak.

Lenzs law tells us that an induced emf generates a current in a direction which opposes the change in flux which caused the emf in the first place. Connect the unknown inductor parallel to the oscilloscope fig. Youll need to read the peak current in amperes and the amount of time between voltage pulses in microseconds.

Method 1 impedance comparison to resistor the first is to place the inductor in series with a known resistor of good precision for example a 100 ohm 1 resistor is a good choice. Connect the 50 ohm output of the function generator to the oscilloscope and select a sine wave signal. This is the amount of inductance of the device being tested.

Connect a resistor of known resistance and the coil in series with the sine wave oscilloscope. The best way to measure inductance for an inductor like a coil solenoid is to use an inductance bridge or meter.
