Typo alert: Read the end of this "description". Before we begin the study of electric/electronic circuits in AC steady state, let's lay down the fundamental framework: a quick review of complex numbers. What they are, why they are, the six ways of representing them. How to add, subtract, multiply and divide them? This is the preface to phasor analysis of circuits. TYPO ALERT: In 36:22 and following, while capturing the ton (23) of screenshots of the calculator for the sequence, I must have got one in which the Is1 was missing from the KCL1 equation. The actual V1c (voltage Vo) is (in rectangular) 5.99 - 0.83j or in polar 6.04/-7.92 deg. Do watch the ADDENDUM at [ Ссылка ]
