For the circuit diagram shown, V1 = 2.5 V, V3 = 5.0 V, 12 = 0.30 A, 13 = 0.50 A, 14 = 0.10 A, and R4 = 70.0 ohms Find Vsource, V2, V4, V5, Isource, I1, Is, R1, R2, R3, Rs, and Rtotal. Indicate, where appropriate, what laws you used to find the various values if a calculation was not required (i. e. KVL/KCL).​
