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 lines are lines in a plane that do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be 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 is mixed. In series, $ R»nr $ and in parallel, the external resistance is negligible.
