The circuit current will have a phase angle somewhere between 0° and +90°. Parallel AC circuits exhibit the same fundamental properties as parallel DC circuits: voltage is uniform throughout the circuit, branch currents add to form the total current, and impedances diminish (through the reciprocal formula) to form the total impedance.
If we connect the RC circuit to a DC power supply, the capacitor will start to collect electric charge until it gets fully charged. The time it takes depends on the capacitance of the capacitor C C C and the resistance of the resistor R R R controlling the current, which is the amount of charge ending up in the capacitor per one second.. The larger the capacitance or …
The shock absorber damps the motion and dissipates energy, analogous to the resistance in an RLC circuit. The mass and spring determine the resonant frequency.

Power Factor Correction is a technique which uses capacitors to reduce the reactive power component of an AC circuit in order to improve its eficiency and reduce current.. When dealing with direct current (DC) circuits, the power dissipated by the connected load is simply calculated as the product of the DC voltage times the DC current, that is V*I, given in …

We can see from the above examples that a capacitor when connected to a variable frequency supply, acts a bit like a frequency controlled variable resistance as its reactance (X) is "inversely proportional to frequency". At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect of an open circuit).
