lov A4 1-31,5-4 Po ® find ix (use superposition) 30V

Answer 1

Supesposition the arem Case-1:- Acting 30v source alone 62 - 42 sovo 62 Bove by ohn's laco, v= 6ix, 0 Apply nodal analysis at v * + V-30 +8+4= 0. 7 V + V-30 +4892 = 0 9 2V-30 + 489x, = 0 » [6ix] -307 48 in = 0 – Goix, = 30 lix, = 0.5A Case-2:- Acting 3A Source alone @A a

By Scurte transformation, V= IR V = 3x4 V=12 volts 12 V Giş by ohan's law V+12 ^ = v= 6iq-12 → 0 Apply nodal analysis aut v. + V +12 + 8 = 0. = V+ V +12 +421x=0 = 2V +12 +481x = 0 => 2 [6i-12) +12 +4812= 0 ħ 12ix +48i4 = 12 =) P = 0.2A According to superpolition Theorem, [from Case-1 & case 2] π ix = 0.5 +0.2 12=0.7 A
