Problem 2 - 15 Points. Using node-voltage analysis, solve for the indicated unknowns in the following figures. Hints: In parts (a) and (b), note that kV, mA, and volts make a consistent set of units; in part (c), find Va, then V10 from the voltage divider. 10 V 3 ΚΩ 2 ΚΩ + 1 mA 20 ΚΩ 1 mA v = ? 2 ΚΩ > 10 ΚΩ 4 mA 40 ΚΩ (a) 10 Ω a 100 V 20 Ω (b) 40 Ω 10 Ω 10 50 Ω +
