A parallel combination of 0.1 `M Omega` resistor and a `10muF` capacitor is connected across a 1.5 V source of negligible resistance. The time (in sec) required for the capacitor to get charged upto 0.75 V is approximately

Options

A. `log_(2)2`
B. `oo`
C. zero
D. `log_(10)2`

Answer

C

Explanation

In this case, the capacitor plates are directly connected to the battery and there is no resistance in the part of the circuit containing C and E. thus no time is required for charging.
or `tau=RC=0xxC=0`
