Kirchhoff's law

In the circuit shown in Figure A, all resistors are 8 Ω, and the internal resistance of each battery is 3 Ω. Other parameters are shown on the circuit diagram.

a) Determine the values of the currents that flow through each resistor R1, R2, R3, and R4.
The directions of the current through each resistor should be indicated by arrows on the circuit diagram.

b) Determine the reading of a voltmeter connected between the points A and B.

c) Determine the amount of charge accumulated on the capacitor C1. What is the sign of the charge on the left-hand-side plate of the capacitor?
