An old Electronics Designer’s Casebook described a circuit that provided capacitance measurements of 10 pF to 1 µF with 1% accuracy (Reference 1). A number of issues emerged with the circuit during ...

When you develop the prototype of a circuit using capacitors or when you replace an old, defective capacitor with a new one, you often need to know the value of the capacitor you use or replace. At ...

Building a capacitance meter is a great exercise. If you’re feeling quite safe in your digital-circuit-only life, this will push just far enough out of the comfort zone for you to see there’s nothing ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...
