Last month, we showed how you could use vector diagrams and simple math to calculate neutral currents in 3-phase, 4-wire circuits. In this last installment, we'll talk about using simple parallelogram ...

A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...

If you work in the professional audio field, you need to use balanced lines for long signal runs to prevent hum and noise pick-up. This Balanced/Unbalanced Converter is really two projects in one. It ...
