What else can I help you with?
Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
Can inductive reactance be in kilo ohm?
Yes. Inductive and capacitive reactance is measured in ohms, and it is entirely possible for reactance to be greater than 1,000, or even 1,000,000, ohms. It all depends on frequency.
How can capacitive reactance be calculated?
it depends on capacitance and frequency, both inversely. Check your AC circuits textbook for the exact equation.
How do you write out an equation used to find the inductive reactance ant the capacitive reactance?
Xc(capacitive reactance) = 1/(2piFC)XL(inductive reactance) = 2piFLWhere pi=3.14etc.,F=frequency and C and L are capacitance and inductance.Please pardon lack of proper symbology.
Why does the inductor have impedance at high frequencies?
An inductor has impedance at high frequencies because its reactance, which is a measure of how much it resists changes in current, increases with frequency. This reactance is given by the formula (X_L = 2\pi f L), where (f) is the frequency and (L) is the inductance. As the frequency increases, the inductor opposes rapid changes in current more effectively, resulting in higher impedance. This behavior makes inductors useful in filtering applications, where they can block high-frequency signals while allowing lower frequencies to pass.
What is difference between impedance and reactance?
Impedance is the net reactance(for Capacitors and inductors in the circuit) / Resistance of the circcuit whereas reactance is the prperty of the individual passive components ( only capacitors n inductors) to resist the flow of charge.
Why is there no inductive reactance in DC circuits?
Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.
Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
Is inductive reactance directly or inversely proportional to frequency?
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
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.
What is the reactance offered by a capacitor of freqency 100hz?
The reactance of a capacitor depends on its capacitanceand the frequency of the voltage across it.In general, the magnitude of capacitive reactance is . . .1 / (2pi x frequency x capacitance)At 100 Hz, that would be0.00159 / (capacitance) in Farads .
Can inductive reactance be in kilo ohm?
Yes. Inductive and capacitive reactance is measured in ohms, and it is entirely possible for reactance to be greater than 1,000, or even 1,000,000, ohms. It all depends on frequency.
How does doubling the frequency effect the reactance of an inducter and capacitor?
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
What factors affect the reactance of a capacitor?
Reactance (in ohms) = 1/(2 pi * capacitance * frequency). Capacitance is in farads. Frequency is in Hertz (cycles/second). So increasing capacitance or increasing frequency will decrease reactance.
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
How can capacitive reactance be calculated?
