In the figure below, determine the current in each resistor, the potential difference across the 2.00 x 10^2 Ω resistor, and the power delivered by each battery. (Due to the nature of this problem, do not use rounded intermediate values in your calculations.)
HINT
A circuit consists of three adjacent rectangular loops arranged in a horizontal row. The left side of the leftmost loop has a resistor of resistance 2.00 x 10^2 Ω. The right side of the leftmost loop, which is the left side of the loop in the middle, has a battery of potential difference 40.0 V above a resistor of resistance 80.0 Ω. The positive terminal is above the negative terminal. The right side of the loop in the middle, which is the left side of the rightmost loop, has a battery of potential difference 3.60 x 10^2 V above a resistor of resistance 20.0 Ω. The negative terminal is above the positive terminal. The right side of the rightmost loop has a battery of potential difference 80.0 V above a resistor of resistance 70.0 Ω. The positive terminal is above the negative terminal.
