Vedclass · Answer

(C) According to Kirchhoff's Current Law $(KCL)$,the sum of currents entering a junction equals the sum of currents leaving it.Applying $KCL$ at the first junction:$I_4 = 1 	ext{ A} + 2 	ext{ A} + 3 	ext{ A} = 6 	ext{ A}$Applying $KCL$ at the second junction:$I_6 = I_4 - 1.2 	ext{ A} = 6 	ext{ A} - 1.2 	ext{ A} = 4.8 	ext{ A}$Applying $KCL$ at the third junction:$I_8 = I_6 + 0.8 	ext{ A} = 4.8 	ext{ A} + 0.8 	ext{ A} = 5.6 	ext{ A}$Applying $KCL$ at the final junction:$I = I_8 - 0.5 	ext{ A} - 1.7 	ext{ A} = 5.6 	ext{ A} - 2.2 	ext{ A} = 3.4 	ext{ A}$
