How do you draw a RLC circuit?

For a series RLC circuit, and impedance triangle can be drawn by dividing each side of the voltage triangle by its current, I. The voltage drop across the resistive element is equal to I*R, the voltage across the two reactive elements is I*X = I*XL – I*XC while the source voltage is equal to I*Z.

What is RLC series circuit?

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. In this role, the circuit is often referred to as a tuned circuit. An RLC circuit can be used as a band-pass filter, band-stop filter, low-pass filter or high-pass filter.

How do you draw a phasor diagram in a circuit?

All phasors are drawn referenced to the horizontal zero axis. Phasor diagrams can be drawn to represent more than two sinusoids. They can be either voltage, current or some other alternating quantity but the frequency of all of them must be the same. All phasors are drawn rotating in an anticlockwise direction.

Is LCR and RLC circuit same?

Is there a difference between RLC circuit and LCR circuit? There is no difference between an RLC circuit and an LCR circuit except for the order of the symbol represented in the circuit diagram.

What is XL and XC in RLC circuit?

In general for RLC series circuit impedance is given by, Z = R + j X. X = XL – Xc = Total reactance of the circuit. If XL > Xc ; X is positive & circuit is Inductive. If XL < Xc ; X is negative & circuit is Capacitive.

What is bandwidth in series RLC circuit?

The bandwidth of any system is the range of frequencies for which the current or output voltage is equal to 70.7% of its value at the resonant frequency, and it is denoted by BW. Figure 8.9 shows the response of a series Bandwidth of RLC Circuit.

Why do we use phasor diagram?

The purpose of a phasor diagram is to provide an efficient graphical way of representing the steady-state inter-relationship between quantities that vary sinusoidally in time. We picture all phasors to be rotating anticlockwise at a constant speed and completing one revolution per cycle of the supply.

What is pure inductive circuit?

The circuit which contains only inductance (L) and not any other quantities like resistance and capacitance in the circuit is called a Pure inductive circuit. In this type of circuit, the current lags behind the voltage by an angle of 90 degrees.

What is the principle of LCR circuit?

This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction. The result is an oscillation, or resonance.

What happens in LCR circuit?

In an LCR circuit, this frequency is determined by the values of inductance, conductance, and resistance. In LCR series circuits, resonance occurs when the value of inductive and capacitive reactances have equal magnitude but have a phase difference of 180°. Thus, they cancel each other.

What is Q factor in LCR circuit?

Q-factor: In LCR Circuit, the ratio of resonance frequency to the difference of its neighbouring frequencies so that their corresponding current is 1/2 ​ times of the peak value, is called Q-factor of the circuit.

How to calculate the RLC circuit, phasor diagram?

For the given circuit diagram calculate the RLC series circuit impedance, current, voltage across each component, and power factor. Also draw the phasor diagram of current and voltage, impedance triangle, and voltage triangle. First of all, let me calculate the total impedance with the following formula

What kind of circuit is series RLC circuit?

The resulting circuit is called series RLC circuit. A circuit and phasor diagram for a series RLS circuit has been shown below. The phasor diagram of series RLC circuit is drawn by combining the phasor diagram of resistor, inductor and capacitor.

How is the sinusoidal response of a series RLC circuit determined?

The series RLC circuit above has a single loop with the instantaneous current flowing through the loop being the same for each circuit element. Since the inductive and capacitive reactance’s XL and XC are a function of the supply frequency, the sinusoidal response of a series RLC circuit will therefore vary with frequency, ƒ.

When to use the impedance triangle in the phasor diagram?

The impedance triangle of the RL series circuit, when (X L > X C) is shown below If the inductive reactance is greater than the capacitive reactance than the circuit reactance is inductive giving a lagging phase angle. Impedance triangle is shown below when the circuit acts as a RC series circuit (X L < X C)
