Expert Answer
Charge on each capcitor at time t, Q = E C { 1 - e-t/(2RC) }
Note that time constant is doubled due to parallel connection of capacitors .
E is EMF of battery, C is capacitance of individual capacitors and R is resistance in the circuit.
...............(1)
using approximation e-x = 1 - x , when x << 1, above equation becomes,
Q = 12 × 2 × 10-6 C = 24 μC
