In a pure capacitor the current leads the voltage by 90°, while in a pure inductor the current lags the voltage by 90°. If the resistance of an RC circuit is increased, the resistive current will be decreased and the circuit will become more capacitive and the phase angle will become larger.

Customer ServiceWhen a capacitor and a resistor are connected in parallel across a voltage source, they behave independently of each other. This means that the same voltage is applied to both components. Key Characteristics: Voltage: The voltage across both the resistor and the capacitor is the same, equal to the source voltage.
Capacitive Reactance (Xc): This is the opposition offered by a capacitor to the flow of AC current. It’s inversely proportional to the frequency of the AC signal and the capacitance of the capacitor. Xc = 1 / (2πfC) where: In summary, while a capacitor doesn’t have a fixed resistance, its impedance varies with the frequency of the AC signal.
Capacitors are one of the most common circuit components. Why it’s important: Capacitors store electrical energy, and you can increase the capacitance of a system by placing capacitors in parallel. In this lesson, we will learn that capacitors in parallel add to the capacitance in the system in a similar way to placing resistors in series.
Voltage: The voltage across both the resistor and the capacitor is the same, equal to the source voltage. Current: The total current flowing into the parallel combination is the sum of the currents flowing through the resistor and the capacitor.
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,
Real-World Considerations: Parasitic Resistance: Even in the most ideal circuit, there will always be some resistance, whether it’s from the wires, the internal resistance of the voltage source, or the ESR (Equivalent Series Resistance) of the capacitor itself.
