Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

While LCR meters are readily available at reasonable cost, they do not measure the Q of an inductor. This circuit enables you to measure the Q of inductors with the aid of an RF signal generator. A ...

Just as tuning forks, gongs, and other elastic solids can show physical resonance, the crystal can be used as an electrical resonator. A quartz crystal’s electrical equivalent model is that of a ...
