Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
What is the capacitive resistance of a 0.04 microfarad capacitor in ac circuit that has a frequency of 1000 hz?
The capacitive reactance is approximately 4 kΩ .
Why at resonance the voltage drop across inductance and the voltage drop across capacitance is greater than the source voltage?
This isn't necessarily the case. It depends upon the value of resistance (which, at resonance, determines the current), and the values of the inductive- and capacitive-reactance.At resonance, the impedance of the circuit is equal to its resistance. This is because the vector sum of resistance, inductive reactance, and capacitive reactance, is equal the the resistance. This happens because, at resonance, the inductive- and capacitive-reactance are equal but opposite. Although they still actually exist, individually.If the resistance is low in comparison to the inductive and capacitive reactance, then the large current will cause a large voltage drop across the inductive reactance and a large voltage drop across the capacitive reactance. Because these two voltage drops are equal, but act the opposite sense to each other, the net reactive voltage drop is zero.So, at (series) resonance:a. the circuit's impedance is its resistance (Z = R)b. the current is maximumc. the voltage drop across the resistive component is equal to the supply voltaged. the voltage drop across the inductive-reactance component is the product of the supply current and the inductive reactancee. the voltage drop across the capacitive-reactance component is the product of the supply current and the capacitive reactancef. the voltage drop across both inductive- and capacitive-reactance is zero.
What is a purely capacitive circuit means?
A 'purely capacitive' circuit is a theoretical, or 'ideal', circuit, in which the resistance and inductance of the circuit is ignored, and in which the load current theoretically leads the supply voltage by exactly 90 electrical degrees. It is often used as a means of introducing students to the behaviour of 'real' a.c. circuit which contain contain resistance and inductance, as well as capacitance.
Why current is maximum in series resonance circuit?
Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.

What is the reason that capacitive reactance measured in ohms?
Because it is. Capacitive reactance is a form of resistance, along with inductive reactance. All are measured in ohms.

The capacitive reactance is approximately 4 kΩ .
What is relationships of capacitive reactance to resistance?
when ever current passing through any two parallel transmission line than due to the dieletric property of conductor some what capacitance effect will be generate between them that phenomina called as capitance reactance/////////////////// that symply we can called capitance reactance is measure of capitance The reactance of a capacitor is its resistance.
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 meant by susceptance in electrical engineering?
Susceptance is the reciprocal of reactance, and is expressed in siemens (symbol: S). So, inductive susceptanceis the reciprocal of inductive reactance, and capacitive susceptance is the reciprocal of capacitive reactance.

What is capacitor reactant?
Capacitive reactance is an opposition to changes in voltage across an element. This resistance is usually caused by a magnetic field.
An opposition to current flow that occurs in alternating current circuits is called?
Capacitive reactance.
Why does the resistance in a series resonant circuit have no bearing on the resonant frequency?
Series resonance occurs when a circuit's inductive reactance is equal to its capacitive reactance. The resistance of the circuit is irrelevant.WebRep currentVote noRating noWeight
