Consider RLC series circuit :
Consider RLC series circuit :
a pure resistance R, a pure inductance L and a pure capacitance C are connected in series.
r.m.s value of applied voltage = V Current through R and L = I
Reference phasor = I (Same current ) Voltage drop across the resistance = VR=I R
(in−phase with current )
Voltage drop across the inductor = VL=I XL
(I lags the V by 90° )
Voltage drop across the capacitor = VC=I XC (I leads the V by 90° )
Voltage V = Vector sum of VR ,VLand VC
Power triangle:
The relationship among active power, reactive power and apparent power is illustrated by a right angled triangle called the power triangle. Reactive power is the vertical axis of the triangle, active power i s the horizontal axis and apparent power or total power is the hypotenuse.
Active Power:
When an active component of current is multiplied with circuit voltage, it results in active or true power. This power produces torque in motors, heat in heat ers, light in lamps etc., Further wattmeter indicates this power.
Reactive Power:
When a reactive component of current is multiplied with circuit voltage, it results in reactive power. This power flows back and forth without doing any work. This p the power factor of the circuit.
Apparent Power:
ower determines When the circuit current is multiplied with circuit voltage, it results in apparent power. i.e product of voltage and current.
In a.c circuit, there is phase difference between voltag e and current so that product of voltage and current does not give real power. To avoid confusion, it is measured in voltampere.
Power Factor: From power triangle, the power factor may also be determined by taking the ratio of true power to apparen t power. Power Factor = True Power or Active Power Apparant Power .
