A capacitor of capacitance \( C \) is charged by a battery whose internal resistance is \( R \). The time after which potential difference across resistor becomes \( n \) times to that across capacitor is
(a) \( R C \ln \left(\frac{1+n}{n}\right) \)
(b) \( R C \ln \left(\frac{n}{1+n}\right) \)
(c) \( R C \ln \left(\frac{n}{n-1}\right) \)
(d) \( R C \ln (1+n) \)
