A student connects three identical lamps, each of resistance RRR, to a cell of electromotive force (emf) V V\,V and negligible internal resistance. The student sets up four different circuit configurations, labeled A, B, C, and D, as shown in the diagram below.
Which circuit configuration draws a total current of 2V3R\displaystyle \frac{2V}{3R}3R2V from the cell?
A
B
C
D
