Once again, the parallel impedance formula looks like this: The only drawback to using this equation is the significant amount of work required to work it out, especially without the assistance of a calculator capable of manipulating complex quantities. Regardless of how we calculate total impedan...
In this circuit above, the AC supply voltage is 120V. Therefore, 120V will be divided between both of these capacitors in series. To calculate how we find each voltage, we first calculate the impedances of the capacitors. Again, using the reactance formula,XC= 1/(2πfc), we calculate th...
Check the result with our capacitive reactance calculator! Wow, relatively painless, wasn't it? FAQs What is the capacitive reactance if C = 15 nF and f = 60 Hz? 176.84 kΩ. Using the capacitive reactance formula: X = 1 / (2 ×π× f × C) you can replace C = 1.5 ×10⁻⁸...
No, a capacitor cannot convert AC to DC by itself. However, you can use acapacitive transformerless power supplyto make this conversion. This power supply has onedropper capacitorthat reduces the AC voltage using its capacitive reactance and a second capacitor thatsmoothsa pulsating DC into a mor...
