His multimeter doesn’t have an inductance testing function, but he does have a 555 timer on hand. He put the 555 and some other parts together to create his own L meter. The writeup includes the ...

However, characterizing one hypothetical coil you just made is quite tricky as its inductance will depend on the measurement frequency and DC bias current. That’s why [ChaN] designed the circuit ...

Waveform measurements with DC and AC meters as well as advanced use of the oscilloscope are also discussed. Experiments are integrated with Circuit Theory II. Experiments cover: Kirchhoff's laws for ...
