How will be phasor diagram if XL equals XC?

When the inductive reactance (XL) equals the capacitive reactance (XC) in an AC circuit, the circuit is said to be in resonance. In a phasor diagram, the voltage phasor across the inductor (V_L) and the voltage phasor across the capacitor (V_C) will be equal in magnitude but opposite in direction, effectively canceling each other out. As a result, the total voltage phasor will be aligned with the current phasor, indicating that the circuit behaves as purely resistive at this point. The current phasor will lead the voltage phasor by 90 degrees in an inductive circuit and lag in a capacitive circuit, but at resonance, they are in phase.


What is the condition for LCR circuit?

In an LCR circuit, which consists of an inductor (L), capacitor (C), and resistor (R) in series or parallel, the condition for resonance occurs when the inductive reactance (XL) equals the capacitive reactance (XC). This can be mathematically expressed as (XL = XC), or (\omega L = \frac{1}{\omega C}), where (\omega) is the angular frequency. At resonance, the circuit exhibits maximum current and minimal impedance, resulting in a peak response at a specific frequency known as the resonant frequency.


What is the capacitive reactance of a 100 µF capacitor at a frequency of 60 Hz?

XC = -1 / (2 pi f C)XC = about -2653 ohmsThe minus sign indicates the current is leading in the this case. Treat it as if the sign were not there.


What is the relationship between resistance and capacitance in a clc circuit?

The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.


What is resonance frequency in electronics?

The frequency at which the impedance of the circuit becomes zero is known as resonance frequency. Actually at resonance resistance only presence in the circuit. That means the impedance of the inductor and capacitor will automatically vanish.

How are the capacitors treated in the dc equivalent circuit of an amplifier?

In dc equivalent circuit of an amplifier all capacitors are replaced by open circuit because capacitor block dc. As , Xc=1/2πfC We know that that frequency of dc is zero so Xc will infinite so we replace all capacitors with open circuit.


What is the purpose of a blocking capacitor?

At high frequency, capacitor can be considered as 1. Short Circuit in AC analysis. 2. Open Circuit in DC analysis. {because Xc= 1/(2*f*pi) where f= supply frequency,pi=3.14} As at high frequencies, in DC analysis, capacitor will be open circuited & can block the DC signal while AC signal is allowed to pass through.. Hence, this capacitor will act as a blocking capacitor for DC supply.

What two factors determine the capacitive reactance of a capacitor?

The two factors that determine the capacitive reactance of a capacitor are the frequency of the alternating current passing through the capacitor and the capacitance value of the capacitor. Capacitive reactance (Xc) is inversely proportional to the frequency (f) and directly proportional to the capacitance (C), as calculated using the formula Xc = 1 / (2πfC).
