question_answer
A cell of \[e.m.f.\] \[1.5\,V\] having a finite internal resistance is connected to a load resistance of \[2\,\Omega \]. For maximum power transfer the internal resistance of the cell should be [BIT 1988]
A) 4 ohm
B) 0.5 ohm
C) 2 ohm
D) None of these
Correct Answer:
C
Solution :
For maximum power, external resistance = internal resistance.
