Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...

Back in 1948, the journal Physical Review published a paper entitled “Space-Time Approach to Quantum Electrodynamics” by a young physicist named R.P. Feynman at Cornell University. The paper described ...

NOT many years ago a certain type of journalist used to compare and contrast the theorist and the practical man, to the demolition of the former and the apotheosis of the latter. Fortunately, such an ...

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 ...

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 ...
