question_answer15)
(a) Six lead-acid
type of secondary cells each of e.m.f. 2.0 V and internal resistance 0.015
are joined in series to prop supply to a resistance of 8.5.
What are the current drawn from the s u and its terminal voltage? (b)
A secondary cell after long use has an e.m.f. of 1.9 V and a large internal resistance
of 380 . What maximum
current can be drawn from the cell? Could the cell drive the starting motor of
a car?
