An 80μC charge is given to the 4μF capacitor in the circuit shown in Fig. so thae upper plate A is positively charged. An unknown resistance R is connected in the left limb. As soon as the switch S in the central limb is closed, a current of 2 A flows through the 2Ω resistor in the central limb. The capacitive time constant for the circuit is

The current enters at A and comes out at D. Some of the resistance are shown. What should be resistance of wire CB so that it draws double of the current that enters the wire BF.
