A 5-step lesson. Step 1: 'Kirchhoff's Current Law (KCL) - Junction Rule: The sum of currents entering a junction equals the sum of currents leaving. ΣI_in = ΣI_out. Based on conservation of charge.' Step 2: 'KCL example: At a junction, I₁=3A enters, I₂=1A and I₃=? leave. I₃ = 3-1 = 2A.' Step 3: 'Kir
