Use Kirchhoff’s rules to analyze the circuit in Figure P19.56. (a) Let be the branch current though be the branch current through be the branch current through Write Kirchhoff’s loop rule relation for a loop that travels through battery 1, resistor 1, and resistor 3. (b) Write Kirchhoff’s loop rule relation for a loop that travels through battery 2, resistor 2, and resistor 3. (c) Apply Kirchhoff’s junction rule to the junction at A to get a relation between the three branch currents. (d) You should now have three equations and three unknowns Solve for the three branch currents.
