Voltages parallel to a capacitor may also be found when there is no flow of current. (iii). A capacitor has a capacity to store charge. (iv). It has become clear from i = C dv / dt that a current in a capacitor exists at a time when voltages found parallel to it, change with the time.
Can a capacitor be charged in parallel with a resistor?
Charging a capacitor in parallel with a resistor from a constant current source.

I have a subcircuit which is simply a capacitor connected in parallel with a resistor, and supplied by a constant current source.
What happens if two capacitors are connected in parallel?
The amount of charge stored in a capacitor is directly proportional to the charging current flowing through it. When two or more capacitors are connected in parallel, the circuit still behaves as a single capacitor, but the total capacitance increases.

How to calculate the total capacitance of a parallel circuit?

Does a capacitor have a linear charge?
Unfortunately this doesn't seem to be the case, presumably because with a constant current, the charge of the capacitor alone is essentially linear until the max voltage of the supply. It would be linear only if ALL of the current from the current source goes into the capacitor. But it doesn't.
What is a parallel capacitor circuit?
