The figure below shows a battery connected to a circuit. The potential difference across the battery and the resistance of each resistor is given in the figure. 25.0 V 10.5 Ω 10.5 Ω 4.00 Ω 4.00 Ω 20.0 Ω A rectangular circuit begins at its left side at a 25.0 V battery with the positive terminal on top. From the battery, the circuit extends up and to the right to point b. The circuit continues rightward from point b and splits into three parallel vertical branches. The leftmost branch has a resistor labeled 10.5 Ω, the middle branch has a resistor labeled 4.00 Ω and the rightmost branch, from top to bottom, goes through a resistor labeled 4.00 Ω, point c, and a resistor labeled 20.0 Ω. The three branches recombine, the circuit extends to the left passing through point a, bends upward to a resistor labeled 10.5 Ω and reaches the negative terminal of the battery. (a) What is the magnitude of the potential difference (in V) between points a and b in the circuit?   (b) What is the…
