Convider the following tesistor network: Suppose R1=3,R2=4n,R3=2n.R1=4.R1=30V,E2=12V,I1=7A and I27A. Set up and solve a linear sitem for the loop currents and the vollage acoss the cament sourtes as shown in the online notes, you may want to solve the tesulting system with Marus. a. find the loop current in (posthe for dockwie direction) b. Find the loop ourents i3i3 and is iposane for dockwie directionk c. Which direction does curtent flow across each of the resisters? Match with the followng choices. Resistor R1 ? Resistor R2 ? Pesintor R3 Pesistor R4 ? A: from top to bottom B: from bottom to top C: no current
