Let's analyze the given two-mesh circuit step by step, treating i1 as the clockwise mesh current in the left loop and i2 as the clockwise mesh current in the right loop. Option 1: i1 = 11.58 A; i2 = 4.31 A This option matches the values we obtain when solving the two-mesh equations below. We'll derive those exactly so you can see why this is correct. Option 2: i1 = 6.31 A; i2 = 1.58 A If we plug these numbers into the KVL equations (or attempt to solv......Login to view full explanation
