KONTRAK KULIAH MIDDLE TEST/UTS = 35% ASSIGMENT/TUGAS = 15% PARTICIPATIONS = 10% FINAL EXAM/UAS = 40% TOTAL = 100%

3
INTRODUCTORY ALTERNATING CURRENT PEMBANGKITAN TEGANGAN AC

4
TWO EXPRESSION Vm = MAKSIMUM VOLTAGE Vrms= V = Vm/√2 vector representation y(t) is a periodic function of time t, with period T

5
AN IDEAL RESISTOR IN AC CIRCUIT E= Ri i = E/R = (V m /R) sin ωt = I m sin ωtatau I = E/R
