Current Electricity Charging Discharging Of Capacitors Question 126
A 12 V lead accumulator is being charged using 24 V supply with an external resistance $ 2,\Omega $. The internal resistance of the accumulator is $ 1,\Omega $. Find the time in which it will store 360 Wh energy.
Options:
A) 1 hour
B) 7.5 hr
C) 10 hours
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ i=\frac{24-12}{3}=4,A $ , Time of charging $ t=\frac{360}{V,.,i} $
Therefore $ t=\frac{360}{12\times 4}=7.5hours. $
