(a) Six lead-acid type of secondary cells, each of emf 2.0 V and internal resistance 0.015 Omega are joined in series to provide a supply to a resistance of 8.5 Omega . What are the currents drawn from the supply, and its terminal voltage? (b) A secondary cell after long use has an emf 1.9 V and a large internal resistance of 380 Omega . What maximum current can be drawn from the cell? Could the cell drive the starting motor of a car?

(a) Six lead-acid type of secondary cells each of emf 2-0 V and internal resistance 0-015Omega are jouned in series to provide a supply to a resistance of 8-5Omega . What are the current drawn from the supply and its terminal voltage ? (b) A secondary cells after long use has an emf of 1-9 V and a large internal resistance of 380 Omega . What maximum current can be drawn from the cell ? Could the cell drive the starting motor of a car ?

A read storage battery is the most impotant type of secondary cell having a lead anode and a grid of lead packed with PbO_(2) as cathode. A 38% solution of sulphuric acid is used as electrolyte. (Density=1.294 g mL^(-1)) battery holds 3.5 L of the acid. During the discharge of the battery, the density of H_(2)SO_(4) falls to 1.139 g mL^(-1).(20%H_(2)SO_(4) by mass) Lead storage battery is considered a secondary cell. Why?

Siix lead-acid type of secondary cells, each of emf 2.0 V and internal resistancce 0.015 Omega are joined in series to provide a supply to a resistance of 8.5Omega . Determine : (i) the current draw from the fupply and (ii) its terminal voltage.
