A schematic diagram showing an ideal DC voltage source labeled \(\mathcal{E} = 12\text{ V}\) on the left vertical branch. Connected in parallel to the right are two vertical branches. The middle branch contains a single resistor labeled \(R_1 = 6.0\text{ }\Omega\). The rightmost branch contains a resistor labeled \(R_2 = 3.0\text{ }\Omega\) in series with a capacitor labeled \(C = 4.0\text{ }\mu\text{F}\). Standard schematic symbols are used for the battery, resistors, and capacitor, with clean rectangular connecting wires forming two parallel loops. No other labels, text, or components appear.
Circuit schematic with two parallel branches.
A circuit consists of an ideal battery with electromotive force (emf) \(\mathcal{E} = 12\text{ V}\) connected to two parallel branches. The first branch contains a resistor of resistance \(R_1 = 6.0\text{ }\Omega\). The second branch contains a resistor of resistance \(R_2 = 3.0\text{ }\Omega\) connected in series with an initially uncharged capacitor of capacitance \(C = 4.0\text{ }\mu\text{F}\). A long time after the circuit is connected, what is the total current supplied by the battery?
