What is the capacitive reactance of a 1 microfarad capacitor at 60 Hz?
A capacitor with a capacitance of 106.1 microfarads is connected to a 120 volt, 60 hertz AC circuit. To determine the current flow in the wire, first find the capacitive reactance of the capacitor. The capacitive reactance equals 1,000,000 divided by 6.28 times 60 hertz times 106.1 microfarads which equals 25 ohms.
What is the capacitive reactance of a 100pf capacitor at 2mhz?
6. Calculate the reactance of a 100-pF capacitor at an operating frequency of 2 MHz? Explanation: Capacitative reactance =Xc= 1/2πfC = 1/(2 x 3.14 x 2 x 106 x 100 x 10-12) = 796.2Ω.
What is the capacitive reactance of the capacitor?
Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor. where 2π =6.28. The symbol for reactance is X. To specify a specific type of reactance, a subscript is used.
What is the capacitive reactance of a 5 pF capacitor at 10 kHz?
For steady DC which is zero frequency, XC is infinite (total opposition), hence the rule that capacitors pass AC but block DC. when the frequency is higher at 10 kHz its reactance is only 16 Ω.
What is the capacitive reactance of a 5 microfarad capacitor when it is a part of a circuit whose frequency is 50 Hz?
When the frequency is 50 Hz, the capacitive reactance is 636.94 Ω.
What is capacitive reactance XC?
The unit of Capacitive Reactance Xc is Ohm. Capacitive reactance is defined as the measure of capacitor’s opposition to alternating current. It is more complex than the resistance as the value depends on the frequency of the signal passing through the capacitor.
When a 60 Hz voltage is applied to a 22 ΜF capacitor the capacitive reactance is?
Transcribed image text: When a 60-Hz voltage is applied to a 22-uF capacitor, the capacitive reactance is O 760 Ω.
What is the reactance of capacitor in a DC circuit?
The capacitive reactance at 1600 Hz is 81 Ω.
How do you find inductive reactance?
The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, 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. XL =2p x f x L.
How do you calculate capacitive reactance?
We can calculate the capacitive reactance X of a capacitor C using the following equation: X = 1 / (2 * π * f * C) .
What is the capacitive reactance for DC voltage?
Since we know for DC power, frequency = zero. The capacitive reactance will be infinite in this case.
What is capacitive reactance XC What is its value for DC?
The reactance is large at low frequencies and small at high frequencies. For steady DC which is zero frequency, Xc is infinite (total opposition), hence the rule that capacitors pass AC but block DC….Capacitive Reactance Xc.

What is the reactance of a 1 µF capacitor?
For example a 1 µF capacitor has a reactance of 3.2 kΩ for a 50 Hz signal, but when the frequency is higher at 10 kHz its reactance is only 16 Ω. The used browser does not support JavaScript. You will see the program but the function will not work. CapacitanceC, frequency f, and capacitive reactance XC
Which is the correct definition of capacitive reactance?
Definition of capacitive reactance: The capacitive reactance is the complex impedance of a capacitor whose value changes with respect to the applied frequency. When a DC (Direct Current) voltage is applied to a capacitor, the capacitor itself draws a charge current from the source and charges to a value equal to the applied voltage.
What happens when the frequency of a capacitor increases?
As the frequency applied to the capacitor increases, its effect is to decrease its reactance (measured in ohms). Likewise as the frequency across the capacitor decreases its reactance value increases. This variation is called the capacitor’s complex impedance.
How to calculate the capacitive reactance of a fluorescent fitting?
How to calculate the capacitive reactance of a single 36 watts fluorescent fitting with a 4uf capacitor connected to an alternate current supply with a frequency of 50Hz. Xc = 1/(2pi*f*C) as mentioned many times.
