**INTRODUCTORY ALTERNATING CURRENT**

PEMBANGKITAN TEGANGAN AC

4
**vector representation**

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

**AN IDEAL RESISTOR IN AC CIRCUIT**

E= Ri i = E/R = (Vm/R) sin ωt = Imsin ωt atau I = E/R

6
POWER IN RESISTOR The instantaneous power dissipated

11
**P is called the average power**

Q is called the reactive power

**POWER FOR PURELY INDUCTIVE CIRCUITS**

13
**POWER FOR PURELY CAPACITIVE CIRCUITS**

14
THE POWER FACTOR
