To draw the maximum current from a combination of cells, how should be the cells be grouped ?
1 Parallel
2 series
3 depends upon the relative values of internal and external resistances
4 Mixed grouping
Explanation:
C If combination are connected in series. Then, current If combination are connected in parallel Where, Series is internal resistance is external resistance.

Find the correct answer.
1 Both primary and secondary cells can be charged
2 Only secondary cells can be charged
3 Only primary cells can be charged
4 None of the above
Explanation:
B A secondary cell is a type of electrical battery which can be charged discharged into a level and recharge many times. Primary cell is a battery that is designed to be used once and discharged and not recharge with electrolyte and reused like secondary cell.

The internal resistance of a dry cell is :
1 equal to that of electrolyte cell
2 smaller than that of electrolytic cell
3 higher than that of electrolytic cell
4 zero
Explanation:
C The internal resistance of dry cells is generally higher than the common electrolytic cells. Dry cells usually have high internal resistance as the primary dry cells are not rechargeable and are generally disposed of after their chemicals have been used up through the cell' internal reaction. Thus, in the case of dry cells, high internal resistance is required to complete the internal reactions. Primary cells, like alkaline batteries, don't normally have fluid inside them, which is why they are after referred to as "dry cells", increasing their internal resistance.
