Capacitors store charge. There are many applications for their use. There is no set amount of capacitors in a circuit since it is application dependent.

Circuit patterns are the collections of transistors, capacitors, and associated components and their interconnections.

In dc equivalent circuit of an amplifier all capacitors are replaced by open circuit because capacitor block dc. As , Xc=1/2πfC We know that that frequency of dc is zero so Xc will infinite so we replace all capacitors with open circuit.
monolithic integrated circuit
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
No. Capacitors need current to charge or discharge. In an open circuit, current is impossible, so they will stay at the last known charge, depending on the amount of leakage current.
