WHAT IS ALTERNATING CURRENT (AC) ?

ACWAVEFORMSACWAVEFORMS V = A. Sin ωt ω = 2.Л. f

SOME COMMON AC WAVEFORMS

MEASUREMENTS of AC MAGNITUDE HARGA RATA-RATA HARGA EFEKTIF / RMS

PHASE SHIFT Vb = 1. Sin(ωt+0) Va = 1. Sin(ωt+0) Vb = 1. Sin(ωt+0) Va = 1. Sin(ωt+90) Vb = 1. Sin(ωt+0) Va = 1. Sin(ωt-90) Vb = 1. Sin(ωt+0) Va = 1. Sin(ωt+180)
