A set of \( n \) equal resistors, of value \( R \) each, are connected in series to a battery of emf \( E \) and internal resistance \( R \) . The current drawn is 1 . Now, the \( n \) resistors are connected in parallel to the same battery. Then the current drawn from battery becomes \( 10 \). The value of \( n \) is
(a) 10
(b) 11
(c) 20
(d) 9
