Two batteries with terminal voltages V = 76.75V and V = 13.5V are attached to a number of resistors as shown in the diagram. Is R. R. www w R. R Zwart R I, ZI The resistors labelled R all have resistance 15.849 and the resistor labelled R has a resistance 86.992. (The input below will accept answers with no more than 1% variation from the correct value.) What are the three currents I, I2 and I3? Use a sign convention where the values are positive if they go in the same direction as the arrows in the diagram and negative if the current goes in the opposite direction.
