What does capacitive reactance oppose?
Inductive 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
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.
Why is capacitive voltage higher than inductive voltage in an R-L-C circuit?
It isn't necessarily so. The capacitive voltage is the product of the current and capacitive reactance, while the inductive voltage is the product of the current and the inductive reactance. So it depends whether the capacitive reactance is greater or smaller than the inductive reactance!
What is definition of impedence?
Impedance is usually written in equations as Z. Impedance is the real resistance (usualyl referred to as R), and the imaginary / reactive opposition (using an imaginary number 'i' or 'j', depending on your area of study). Z = R + j*n, where 'n' is the reactive opposition.Additional AnswerCurrent, in an A.C. circuit, is opposed by the resistance(R) of that circuit and the reactance (X) of that circuit. Reactance may be 'inductive reactance' (XL) or 'capacitive reactance' (XC) -depending on the nature of the circuit.Inductive reactance is directly proportional to the supply frequency; capacitive reactance is inversely proportional to the supply frequency; resistance is independent of frequency.Impedance (Z) is the vector sum (not algebraic sum) of a circuit's resistance and reactance, and may be considered as the total opposition to the flow of A.C. current.Resistance, reactance, and impedance are each measured in ohms.
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.
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 difference in resistance and reactance?
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
What are the three types of opposition to current flow that impedance represents?
There is pure resistance, inductive reactance, and capacitive reactance.
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 .
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
What does capacitive reactance oppose?
Inductive reactance.
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.
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
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 forces can oppose current flowin an ac circuit?
Resistance, capacitive reactance, inductive reactance. Note: None of this is really a "force" - not in the meaning of "force" as used in physics.
When the frequency of an applied voltage is increased the capacitive reactance of a circuit will?
Since capacitive reactance is inversely-proportional to the supply frequency, as the frequency is increased, the reactance will decrease.
