Current Electricity Charging Discharging Of Capacitors Question 734
Question: A battery of e.m.f. 10 V and internal resistance $ 0.5\Omega $ is connected across a variable resistance R. The value of R for which the power delivered in it is maximum is given by
Options:
A) $ 0.5\Omega $
B) $ 1.0\Omega $
C) $ 2.0\Omega $
D) $ 0.25\Omega $
Show Answer
Answer:
Correct Answer: A
