What will be the final charge on the capacitor after the switch is closed and equilibrium has been reached? The source source is shown on the left vertical branch with a switch at the top of the circuit. From the top node, a horizontal wire leads right from the switch to a 15 ohm resistor. To the right of this resistor, a 16 microfarad capacitor is connected vertically. Below the resistor, a 38 ohm resistor connects downward to the bottom return wire. The capacitor and the 38 ohm resistor share a connection point.
