Current Electricity Charging Discharging Of Capacitors Question 474
Question: The heat generated through 2 ohm and 8 ohm resistances separately, when a condenser of 200 $ \mu F $ capacity charged to 200 V is discharged one by one, will be
[MP PET 1993]
Options:
A) 4 J and 16 J respectively
B) 16 J and 4 J respectively
C) 4 J and 8 J respectively
D) 4 J and 4 J respectively
Show Answer
Answer:
Correct Answer: D
Solution:
Heat generated in both the cases will be same because the capacitor has the same energy initially $ =\frac{1}{2}CV^{2}=\frac{1}{2}\times 200\times {{10}^{-6}}\times {{(200)}^{2}}=4J $ F
