Problem
A series circuit carries a clockwise current of 0.50 A through an ideal battery of unknown emf E, followed by resistor R₁ = 4 Ω and resistor R₂ = 6 Ω. A potential–position graph traced in the clockwise direction shows the battery raising the potential from 0 V to +E V, then a 2 V linear drop across R₁, and finally a 3 V linear drop across R₂ before the graph returns to 0 V at the starting point. Calculate the emf E and state whether the assumed current direction is consistent with the potential changes shown.
