SUMMARY
The voltage across each capacitor in the circuit after the switch is closed can be calculated using the equations Q = CV and V = IR. The voltage for the 5 µF capacitor is determined to be 20 V, which is equivalent to the voltage across the 40-ohm resistor due to the steady-state condition in the circuit. For the 10 µF capacitor, the voltage can be derived by analyzing the resistive voltage divider formed by the surrounding resistors once the transient currents have dissipated and the circuit reaches a static state.
