4) In the figure below, all the resistors are the same, but the batteries are different. ww M ww 1 V 2 V 3 V a) Label the diagram as follows: Label each vertical resistor "100 S?" Label each horizontal resistor "200" Label the vertical sections, starting from the left, having currents going downward of 11, 12, 13, 14 respectively. Label the top middle horizontal section having current to the left of 15, and the bottom middle having current to the right of 16. b) Write the junction equation (using those variables) for the junction between the batteries on the left and in the middle. c) Write the loop equation (again, with the same variables) for a clockwise loop [not drawn on the original diagram] going around the whole outer perimeter, and another for a loop counterclockwise in only the center part of the diagram.
