The value of the capacitive reactance of a capacitor depends on the capacitor's capacitance and the frequency at which the capacitor is operated. The reactance of a capacitor is expressed in Ω (SI unit).Answer and Explanation: Identify the ...
The reactance of a capacitor isXC. If both the frequency and the capacitance are double, then the new reactance will be View Solution The reactance of 2 H inductance in an ac circuit of frequency 50 Hz is View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Soluti...
In theory a perfect inductor or capacitor has no resistance. The reactance of a capacitor or inductor is similar to the resistance of a resistor. The biggest difference is that a resistor essentially opposes AC equally at all frequencies. The reactance of a coil (inductor) or capacitor varies ...
Example 1: Must calculate the reactance of a 2.2uF capacitor at 50Hz AC line View example Example 2: Must calculate the capacitance that have 10kohm reactance at 1kHz AC line View example Capacitance farads Frequency hertz Reactance ohms You...
Capacitance, meanwhile, is resistance that occurs when a device such as a capacitor stores an electric charge that resists changes in voltage. Capacitance is measured in farad (F) and symbolized with C. A circuit's reactance can result from inductance, capacitance or a combination of both. ...
The capacitive reactance, a measure of this opposition, is inversely proportional to the frequency f of the alternating current and to a property of the capacitor called capacitance (symbolized by C and depending on the capacitor’s dimensions, arrangement, and insulating medium). The capacitive ...
Capacitive reactance, on the other hand, is associated with the changingelectric fieldbetween two conducting surfaces (plates) separated from each other by an insulating medium. Such a set of conductors, acapacitor, essentially opposes changes in voltage, or potential difference, across its plates. ...
The capacitive reactance is a property of a capacitor. Similarly, inductive reactance is a property of an inductor – check the inductive reactance calculator for a more detailed explanation and formulas. An ideal resistor has zero reactance, while it's a purely resistive element. On the contrary...
