In this section, mutual inductance and importance of the cores will be demonstrated. 1. Measure the resistances of the 0.68 mH and 0.42 mH inductors.
2. Adjust the frequency of the function generator to 60 Hz and let the function generator output voltage be the maximum possible (Around 23.2 Vp-p).
3. Connect the sinusoidal voltage from the function generator to the 0.68 mH inductor and measure the voltage across the inductor.
Note: Due to the very small resistance of the inductance, a very large current is required from the function generator. This function generator cannot provide this high output current and thus cannot sustain the maximum voltage. The voltage falls to a value which can be sustained by the function generator.
