Choose a physically available cell arrangement

Six identical cells each have emf 2 V and internal resistance 1 Ω. They must form equal parallel branches, each with n cells in aiding series, to supply a 1.5 Ω resistor. Allowed n values are 1, 2, 3 and 6.

Which n gives the largest load current?

Organize the givens & assumptions

Six identical cells
Each: 2 V and 1 Ω
Load: 1.5 Ω

Constant ideal emf and positive Ohmic internal resistance over the stated interval; settled DC currents and negligible lead resistance. This is an assigned source model, not battery test data. All cells and equal branches share load symmetrically; no unequal-emf circulating currents.

A $n=6$
B $n=3$
C $n=1$
D $n=2$
