Cells

Six identical cells, Each of emf of 6V, are connected in parallel. The net Emf across the battery is

• 6V

• 36 V

• 0 V

• Between 6V and 36 V

If two identical cells ,when connected in series or in parallel,same current pass through an external resistance of 2 ohm, the internal resistance of each cell is

• 8 ohm

• 2 ohm

• 6 ohm

• 1 ohm

To supply maximum current , cells should be arranged in

• Series

• parallel

• mixed Grouping

• Depends on external and internal resistance

For n cells of emf E each , the equivalent emf of the series combination is ...................... and that of the parallel combination is....................

In a mixed grouping of cells , the current through the external resistance will be maximum if the external resistance is ........the total internal resistance of the cells,
