INTRODUCTORY ALTERNATING CURRENT
PEMBANGKITAN TEGANGAN AC

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

POWER IN RESISTOR The instantaneous power dissipated

P is called the average power
Q is called the reactive power

POWER FOR PURELY INDUCTIVE CIRCUITS

POWER FOR PURELY CAPACITIVE CIRCUITS

THE POWER FACTOR

above

We now calculate P and Q directly

THE RMS VALUE AND POWER CALCULATIONS

EXAMPLE SOLUTION The average power delivered to

EXAMPLE a). Calculate the complex power of the load. b). Calculate the impedance of the load.
