Electrostatics 5 Question 31
33. A parallel combination of $0.1 \mathrm{M} \Omega$ resistor and a $10 \mu \mathrm{F}$ capacitor is connected across a $1.5 \mathrm{~V}$ source of negligible resistance. The time required for the capacitor to get charged upto $0.75 \mathrm{~V}$ is approximately (in second)
(1997, 2M)
(a) infinite
(b) $\log _{e} 2$
(c) $\log _{10} 2$
(d) zero
Show Answer
Answer:
Correct Answer: 33. (d)
Solution:
- Since, the capacitor plates are directly connected to the battery, it will take no time in charging.
