In a circuit shown in the figure, the capacitor C is initially uncharged and the key K is open. In this condition, a current of 1 A flows through the 1 
resistor. The key is closed at time t = t 0 . Which of the following statement(s) is(are) correct? [Given: e -1 = 0.36
.
s, the current in the capacitor is 0.6 A.
, the charge on the capacitor is 12 
C.

(a,b,c,d)
Sol.
By writing voltage drop across 
0+5+1x1=V
V=6
Similarly across R
0+ 15-IxR = 6
IR = 9
across 3 
6 - 3 I 1 = 0
I 1 = 2A
Hence option is correct
1=1+2 (by KCL)
I = 3
IR = 9
R = 3 
Option is correct
