Question

The figure below shows with two batteries and three resistors. The potential difference across the batteries and the resistance of each resistor is given in the figure. 7.50 V 5.46 Ω A rectangular circuit begins at point a on its left side. On its top side, the circuit splits into two parallel horizontal branches. The top branch contains, from left to right, a 12.0 V battery and a 4.00 Ω resistor. The positive terminal of the battery is to the left of its negative terminal. The bottom branch contains a 2.00 Ω resistor. The top and bottom branches recombine to meet at point b, which is to the right of the branches. The right side of the rectangular circuit extends down from the bottom branch, just to the right of the 2.00 Ω resistor and to the left of point b. The bottom side of the rectangle, from right to left, contains a 5.46 Ω resistor and a 7.50 V battery. The positive terminal of this second battery is to the right of its negative terminal.
