Q1 - Electric circuits are described using Kirchoff's voltage and current laws. The electric circuit under consideration is described by the following set of five algebraic equations Ryl + R2i2 - v1 = 0 -R2i2 + Rziz + Rsis = 0 V2 + R414-R3i3 = 0 -11 + 12 + iz + 14 = 0 -14 - iz + is = 0 Calculate the five unknown currents (1) using following resistances (15 pt] R2 = 500 ohms, R2 = 320 ohms, R3 = 600 ohms, R2 = 100 ohms and Rs = 1000 ohms vi = 5V and v2 = 10V
