A single rectangular circuit loop oriented horizontally. The top horizontal segment contains a battery labeled \varepsilon_1 with its longer vertical line (positive terminal) on the right and shorter thicker line (negative terminal) on the left. The right vertical segment contains a zigzag resistor labeled R_1. The bottom horizontal segment contains a battery labeled \varepsilon_2 with its longer vertical line (positive terminal) on the right and shorter thicker line (negative terminal) on the left. The left vertical segment contains a zigzag resistor labeled R_2. No other components, labels, text, or axes appear.
A single-loop circuit containing two opposing batteries and two resistors.
A single-loop circuit contains two ideal batteries with electromotive forces \(\varepsilon_1\) and \(\varepsilon_2\) and two resistors with resistances \(R_1\) and \(R_2\), as shown in the diagram. The electromotive force of the first battery is greater than that of the second battery (\(\varepsilon_1 > \varepsilon_2\)), and the batteries are arranged such that their positive terminals face one another. Which of the following expressions represents the magnitude of the electric current \(I\) in the circuit?
