# What is the symbol for reactance

## What is XL and XC?

In series RLC circuit, the condition XL

**(Inductive reactance) = XC (Capacitive reactance)**is called resonance condition. In this condition the inductive reactance get cancelled by capacitive reactance. So,the entire RLC series circuit just acts as a resistive circuit.## What is the symbol for inductive reactance?

symbol X

_{L}Inductive Reactance which is given the

**symbol X**, is the property in an AC circuit which opposes the change in the current. In our tutorials about Capacitors in AC Circuits, we saw that in a purely capacitive circuit, the current I_{L}_{C}“LEADS” the voltage by 90^{o}.## What is J in reactance?

j is the square root of negative one, and 1/j = -j. j is

**the imaginary number**, used in this case to sort out reactance and impedance from pure resistance. This is because the reactance of a capacitor is a leading reactance. That means that the current leads the voltage across it by 90 degrees.## What is the reactance formula?

When current passes through the coil, an electrical field is generated. … The formula for calculating the inductive reactance of a coil is: inductive reactance, or X

_{L}, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries.**X**._{L}=2^{p}x f x L## What is the capacitive?

pertaining to

**electrical capacitance**, or the property of being able to collect and hold a charge of electricity. exhibiting or relying on electrical capacitance: smartphones with capacitive touchscreens that react to electrical impulses generated by your finger.## What is a capacitive reactance?

**The opposition to the flow of alternating current due to capacitance**is called “capacitive reactance.” It is measured in ohms just like resistance and inductive reactance. … In capacitors, the current leads voltage by 90 degrees.

## How do you calculate Susceptance?

What is Susceptance? As conductance is the complement of resistance, there is also a complementary expression of reactance, called susceptance. Mathematically, it is

**equal to 1/X, the reciprocal of reactance**.## What is the SI unit of capacitive reactance?

ohms

The S.I unit of capacitance is farad, but the S.I unit of capacitive reactance is

**ohms**.## What is the unit of Susceptance?

siemens

In electrical engineering, susceptance (B) is the imaginary part of admittance, where the real part is conductance. The reciprocal of admittance is impedance, where the imaginary part is reactance and the real part is resistance. In SI units, susceptance is measured in

**siemens**.## What letter is commonly used to represent susceptance?

B

Oliver Heaviside coined the term admittance in December 1887.” What letter is commonly used to represent susceptance? There’s no scientific “explanation” for this answer; Susceptance has merely been assigned the

**letter “B”**.## What is transmission line susceptance?

Susceptance (symbolized B ) is

**an expression of the ease with which alternating current ( AC ) passes through a capacitance or inductance**. In some respects, susceptance is like an AC counterpart of direct current ( DC ) conductance . … In the case of an electric field, the susceptance is capacitive.## What is the unit of susceptance 2 points?

As susceptance is the reciprocal of reactance, its unit will be inverse that of the reactance. And we know that the unit of reactance is ohm, hence the unit of susceptance is

**ohm−1**.## What is capacitive admittance?

Admittance is defined as

**a measure of how easily a circuit or device will allow current to flow through it**. … We can say that it is the measure of opposition for the flow of current. In an AC circuit; in addition to the resistance, two impeding mechanisms (inductance and capacitance) have to be considered.## What is inverse reactance?

Similarly, the inverse of reactance is called “

**Susceptance**“. The inverse of impedance is called “Admittance”. Conductance, Susceptance, and Admittance are all denoted by the variables Y or G, and are given the units Siemens.## What is conductance line?

The conductance term represents

**leakage current between the signal wire and the return wire**. this would be in effect the 1/R where R is the internal resistance of the capacitor? The conductance term represents leakage current through the dielectric material.## What is admittance Y?

Admittance (symbolized Y ) is

**an expression of the ease with which alternating current ( AC ) flows through a complex circuit or system**. Admittance is a vector quantity comprised of two independent Scalar phenomena: conductance and susceptance . … Admittance is the vector sum of conductance and susceptance.## What is ΩL?

That is,

**X**just like a resistance does. This is the reason; it is called reactance. Since it is offered by an inductor, it called inductive reactance and indicated by symbol X_{L}= ωL is opposing the flow of current_{L}. … The current through the circuit is equal to (V_{m}ωC)Sin(ωt+π/2).## What is a shunt admittance?

The shunt admittance of a line

**consists of the conductance and the capacitive susceptance**. The conductance is usually ignored because it is very small compared to the capacitive susceptance. The capacitance of a line is the result of the potential difference between conductors.## What is J in jXL?

There is a mathematical tool which uses the “j” operator (it is often called “i” in mathematical books but engineers use “j”). This allows us to write

**Z=R+jXL**or Z= R-jXC – note the minus sign for capacitive reactance, it is important.## What is S in impedance?

The SI unit of admittance is the

**siemens**(symbol S); the older, synonymous unit is mho, and its symbol is ℧ (an upside-down uppercase omega Ω). Oliver Heaviside coined the term admittance in December 1887. Admittance is defined as. where Y is the admittance, measured in siemens Z is the impedance, measured in ohms.## What is a Smith chart used for?

The Smith Chart is used

**to display an actual (physical) antenna’s impedance when measured on a Vector Network Analyzer (VNA)**. Smith Charts were originally developed around 1940 by Phillip Smith as a useful tool for making the equations involved in transmission lines easier to manipulate.## What is W in jwL?

The inductive reactance (Xl) equals jwL, where L is the inductance, and w

**=2(pi)f**.
