Current Electricity Charging Discharging Of Capacitors Question 651
Question: To draw maximum current from a combination of cells, how should the cells be grouped
[AFMC 2005]
Options:
A) Series
B) Parallel
C) Mixed
D) Depends upon the relative values of external and internal resistance
Show Answer
Answer:
Correct Answer: D
Solution:
Maximum current will be drawn from the circuit if resultant resistance of all internal resistances is equal to the value of external resistance if the arrangement s mixed. In series, $ R»nr $ and in parallel, the external resistance is negligible.
