Problem
- What is the KVL Equation for Loop 1? * $-V \mathrm{~S}+\mathrm{V}_{1}+\mathrm{V}_{2}=0$ $-V_{2}+V_{3}+V_{4}=0$ $V s+V_{1}-V_{2}=0$ $V_{2}-V_{3}-V_{4}=0$
Solution
Step 1 ：Analyze each option to determine the KVL equation for Loop 1
Step 2 ：Option 1: \(-V_S + V_1 + V_2 = 0\) is the correct KVL equation for Loop 1
Step 3 ：\(\boxed{-V_S + V_1 + V_2 = 0}\)
