The capacitors in the figure are initially uncharged

The capacitors in the figure are initially uncharged. The capacitances are given, and the battery’s potential difference is given. When the switch is closed, how many electrons travel through points A, B, C, and D?

Tasked with determining the flow of electrons through various points in a circuit with initially uncharged capacitors, Cortez the Capacitor applies the principle of charge conservation and the formula Q=CV to calculate the movement of electrons upon closing the switch. His precise calculations help optimize the circuit's performance.
