4. Consider the following circuit that contains two batteries and three resistors. Rị h- R3. R2 12 a. Use Kirchhoff's first rule-that AV = 0 around a closed loop-to obtain some equations relating the currents. How many independent equations do you find? b. Use Kirchhoff's second rule-that l; = 0 at any node-to obtain some further equations relating the currents. How many independent equations do you find? c. Now solve these equations to determine l1, l2, and 13 in terms of the emfs and the resis- %3D tances.
