The capacitor is a component and its effect is known as capacitance. It has the ability to store energy in the form of an electrical charge. Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. Use our ...
When charging capacitors in series, the same current flows through each capacitor due to the series connection. However, the voltage across each capacitor is not the same. To charge capacitors in series, the total voltage applied across the circuit is divided among the capacitors based on their capacitance values.

15.4 RLC Series Circuits with AC 24. What is the impedance of a series combination of a 50-Ω resistor, a 5.0-μF5.0-μF capacitor, and a 10-μF10-μF capacitor at a frequency of 2.0 kHz? 25. A resistor and capacitor are connected in series across an ac generator.
The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the capacitor will offer 26.5258 Ω of reactance to AC current at 60 Hz. Because the resistor''s resistance is a real number (5 Ω ∠ 0 o, or 5 + j0 Ω), and the capacitor''s reactance is an imaginary number (26.5258 Ω ∠ -90 o, or 0 – j26.5258 Ω), the combined effect of the two …
