PARALLEL RESISTOR-CAPACITOR CIRCUITS Using the same value components in our series example circuit, we will connect them in parallel and see what happens: (Figure below) Parallel R-C circuit. Because the power source has the same frequency as the series example circuit, and the resistor and capacitor both have the same values of resistance and capacitance,
When resistors and capacitors are mixed together in parallel circuits (just as in series circuits), the total impedance will have a phase angle somewhere between 0° and -90°. The circuit current will have a phase angle somewhere between 0° and +90°.
To find the current that is charging the capacitor (in the instant immediately after closing the switch), you can use KCL at the node where the capacitor and the two resistors are all connected. Alternately, you can replace
High value polarised capacitors typically do not have ideal characteristics at high frequencies (e.g. significant inductance), so it''s fairly common to add a low value capacitor in parallel in situations where you need to worry about stability at high frequencies, as is the case with 78xx regulator ICs such as this.

This guide covers The combination of a resistor and capacitor connected in parallel to an AC source, as illustrated in Figure 1, is called a parallel RC circuit.

The capacitor and resistor are connected in parallel so I think that the resistor will draw a current I=VR but the capacitor is an ideal one therefore has no resistance and therefore draws an infinite amount of current which eventually stops when the capacitor is completely charged so overall There is a subtle problem here with the logic.
@ADITYAPRAKASH, if the capacitor is initially not charged, and then you connect it across the resistor, you're right. It will momentarily drop the voltage across that resistor to 0. But no, the current will increase. Because now the whole voltage of the source is across the other resistor. and the current when does it resume then ?
