The figure shows an electrical circuit with an ideal source ε1 = 12 [V], a real source ε2 = 9 [V] and r1 = 1 [Ω], eight resistors and two capacitors. Switches A and B are
They are originally open and the charge on the capacitors is zero.


If switch A closes (B remains open), determine:
a) The currents of the resistors R2 and R5.
b) The potential difference between b and c, that is, Vbc. Indicate which point is at the greatest potential.
c) The power supplied by the real source ε2.
