The amount of charge carried by the capacitor is the absolute value of the amount of charge carried by any plate, but if one plate is grounded,

The amount of charge carried by the capacitor is equal to the voltage difference between the two plates. One plate is grounded, and the charge of the other plate should be something or something. Because in practical application, the capacitor is often connected in parallel at both ends of the resistor to ensure that the voltage at both ends of the resistor is instantaneous, so the voltage at one plate of the capacitor is at least zero, which is equivalent to grounding. For example, the charge of a capacitor is 2 coulombs, one plate is grounded, and the charge of the other plate is still 2 coulombs.
