Unless we're weeding the garden or tripping over one sticking out of the ground, for most of us the root systems of plants are out of sight and out of mind. But, for nearly all plants, roots are ...

Capacitance testers are used to test the capabilities and performance of capacitors, specifically, their ability to hold or store an electrical charge. Capacitance testing is vital to finding leaking ...

First came electronics, the processing of information in terms of the charge of electrons flowing through circuits. Later a new form of tronics, spintronics, was invented to exploit the magnetic ...

Capacitance meters are instruments that measure capacitance, the ability to store an electric charge. They are used to test, inspect and sort ceramic and other types of capacitors on production lines.

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...
