There are a large number of cells available,each marked $(6 \,V, 0.5 \,\Omega)$,to be used to supply current to a device of resistance $0.75 \,\Omega$,requiring $24 \,A$ current. How should the cells be arranged so that power is transmitted to the load using the minimum number of cells?

  • A
    Six rows,each containing four cells
  • B
    Four rows,each containing six cells
  • C
    Four rows,each containing four cells
  • D
    Six rows,each containing six cells
