Kwakwal RLC (Shiyar Kwallon Kai da Diagram na Phasor)

Wani shine Series RLC Circuit?

Series RLC circuit yana da wani resistor, inductor da capacitor suna fi sanya a cikin voltage supply. An samun cikin da ya kira series RLC circuit. A cikin da phasor diagram na series RLS circuit ta shafi a nan.

Phasor Diagram of Series RLC Circuit

Phasor diagram na series RLC circuit yana da shiga da phasor diagram na resistor, inductor da capacitor. Idan ba ta yi haka, zai iya fahimta alaka bayan voltage da current a cikin case na resistor, capacitor da inductor.

1. 
   

1. Resistor
   A cikin resistor, voltage da current suna da phase mafi girma ko zai iya cewa phase angle difference daga voltage zuwa current ita zero.

2. Inductor
   A cikin inductor, voltage da current ba su da phase. Voltage tana da shi da current bayan 90° ko akwai haka, voltage tana samun maximum da zero value 90° bayan current tana samun ita.

3. Capacitor
   A cikin capacitor, current tana da shi da voltage bayan 90° ko akwai haka, voltage tana samun maximum da zero value 0° bayan current tana samun ita, yana nufin cewa phasor diagram na capacitor yana da shi da inductor.

NOTE: Don haka don fahimtar alaka bayan voltage da current, zaka iya karanta kalmar 'CIVIL', yana nufin cewa a cikin capacitor current tana da shi da voltage da voltage tana da shi da current a cikin inductor.

RLC Circuit
Don haka don kawo phasor diagram na series RLC circuit, tabbata wa:

Step – I. A cikin series RLC circuit; resistor, capacitor da inductor suna fi sanya a cikin series; saboda haka, current da ke fito a duk elementoci su da shi, yana nufin I r = Il = Ic = I. Don haka don kawo phasor diagram, zaka iya tabbatar da current phasor da kuma kawo ita a horizontal axis kamar yadda aka shafi a diagram.
Step – II. A cikin resistor, voltage da current suna da phase mafi girma. Saboda haka kawo voltage phasor, VR a cikin axis mafi girma ko direction da ke same da current phasor, yana nufin VR tana da phase mafi girma da I.
Step – III. Ana sanar da cewa a cikin inductor, voltage tana da shi da current bayan 90°, saboda haka kawo Vl (voltage drop across inductor) perpendicular to current phasor in leading direction.
Step – IV. A cikin capacitor, voltage tana da shi da current bayan 90°, saboda haka kawo Vc (voltage drop across capacitor) perpendicular to current phasor in downwards direction.
Step – V. Don haka don kawo resultant diagram, kawo Vc in upwards direction. Kafin kawo resultant, Vs which is vector sum of voltage Vr and VL – VC.

Impedance for a Series RLC Circuit

Impedance Z na series RLC circuit yana nufin opposition zuwa flow of current, saboda circuit resistance R, inductive reactance, XL da capacitive reactance, XC. Idan inductive reactance tana da shi da capacitive reactance, yana nufin XL > XC, then the RLC circuit has lagging phase angle and if the capacitive reactance tana da shi da inductive reactance, yana nufin XC > XL then the RLC circuit have leading phase angle and if both inductive and capacitive are the same, yana nufin XL = XC then circuit will behave as purely resistive circuit.

An sanar da cewa,

Substituting the values VS2 = (IR)2 + (I XL – I XC )2
