A capacitor of capacitance $C = 1 μ F$ is suddenly connected to a battery of $100 V$ through a resistance $R = 100 Ω .$ The time taken for the capacitor to be charged to get $50 V$ is:

(Take $\ln 2 = 0.69$ )

Options:

Answer:

C

Solution:

$V = V_{0} (1 - e^{- \frac{t}{R C}})$
$50 = 100 (1 - e^{- \frac{t}{R C}})$
$t = 0.69 \times 10^{- 4} \sec .$
