Beskrivelse
'Alternating Current -Simply Explained ' uses the author's unique approach to the subject, which explains how anyone with a basic knowledge of d.c. circuits, and who can solve right-angled triangles using Pythagoras's Theorem and the sine, cosine, and tangent trigonometric functions, can learn to thoroughly understand and solve single-phase alternating-current series and parallel circuits, without memorising ANY of the dozens of equations normally associated with this topic. Each chapter shows, using step-by-step examples, how to construct phasor diagrams, from which all necessary equations can then be derived using simple geometry and trigonometry... without the need to memorise those equations
