What two facctors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
What two factors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the alternating current passing through the capacitor and the capacitance value of the capacitor. Capacitive reactance (Xc) is inversely proportional to the frequency (f) and directly proportional to the capacitance (C), as calculated using the formula Xc = 1 / (2πfC).
What is the effect of the magnetic field between capacitor plates on the overall performance of the capacitor?
The magnetic field between capacitor plates does not have a significant effect on the overall performance of the capacitor. The main factors that affect a capacitor's performance are its capacitance, voltage rating, and dielectric material.
What is the total impedance of a circuit with a capacitor in parallel with a resistor?
The total impedance of a circuit with a capacitor in parallel with a resistor is calculated using the formula Z 1 / (1/R 1/Xc), where Z is the total impedance, R is the resistance of the resistor, and Xc is the reactance of the capacitor. This formula takes into account the combined effects of resistance and reactance in the circuit.
How does a capacitor discharge and what factors affect the rate of discharge?
A capacitor discharges by releasing stored electrical energy. The rate of discharge is affected by factors such as the capacitance of the capacitor, the resistance of the circuit, and the voltage across the capacitor. A higher capacitance or lower resistance will result in a slower discharge rate, while a higher voltage will lead to a faster discharge.

The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
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.
Why capacitor will not block ac source?
A capacitor will oppose the flow of a.c. due to its capacitive reactance (Xc), expressed in ohms.The capacitive reactance for a given capacitor is inversely-proportional to the frequency of the supply; in other words, the higher the frequency, to lower the capacitive reactance.
Why does the reactance of a capacitor decrease with frequency?
Because reactance of capacitor is inversly proportional to the frequency i.e- Xc=1/(2*pie*f*c) where f is frequency and c is capacitance of capacitor.
What is the capacitive reactance of a 1 µF capacitor at a frequency of 60 Hz?
The capacitive reactance of a 1 µF capacitor at a frequency of 60 Hz is about 2700 ohms.
Does any capacitor block ac?
It is the capacitive reactance of a capacitor that causes it to oppose the passage of a.c. current. Since capacitive reactance is inversely-proportional to frequency, the lower the frequency, the greater its reactance, and the more it will oppose the flow of a.c.
The reactance of a capacitor is proportional to?
inverse of frequencyAnswerReactance is inversely-proportional to frequency of the supply, and the capacitance of the capacitor.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.
How capacitor behave in alternating current?
Capacitors have an equivalent reactance of 1/jwC (ohms) where w is the angular frequency of the AC signal and C is the capacitance. As the frequency of the signal across the capacitor increases, the capacitor reactance approaches 0 (capacitor acts like a short circuit). As the frequency of the signal across the capacitor decreases, the capacitor reactance approaches infinity (capacitor acts like an open circuit). So, if you have a high frequency signal (like a step input) the capacitor will momentarily act like a short.
What is the definition of capactive reactance?
reactance due to the capacitance of a capacitor or circuit,equal to the inverse of the product of the capacitance and the angular frequency.
