6. Determine the voltages vi and v2 in the circuit below. 14 Ω 2.5 Ω 4 Ω (1)5A , ξ60 Ω να ξ15 Ω 120 3144Ω Λ 10 Ω 5.6 Ω 12 Ω

Answer 1

Answers Circuit 2.5. LM {144 N12 M lo 5.6 la We have to find vi and U₂ . Let's find equivalent Resistance of ... 42, 12-2, 14412, 5.612,122 and 2:52 +2.5 Req = ((4+12) 11 144 +5:6) i 12 11-> Parallel connection Reg a los Equivalent resistance | Rea = 100 l

Putting Rea in einmit 14 1. & Req 10-12 Let's First Find all equivalent nesistance of 102, 14, 15, and 10.2 resistance in above circuit Rü: 14 + (15:1110) +10 Re = 25. Ti s . Re 5. X. 60 trees Ti = 5 X 25 31047 A 60F 25 Ta = 1.47 A - D

- Applying uel 1, = 5-[ : Sml. 47 TT - 3.52 A - Applying current divider 2 = 1 X Ren 15+ Req 23.52 x 10 = 1.411. A 10 H15 Now we know values of I and Iz Vi = Ti x(60-2) volts: V2 = I3 x 15 volts | Putting the values of I and I

V = 147 860 = 88.2 Volts Tv = 88.2 volts = 21.15 Volt Vas 1.41 x 15 V = 21.15 volts 2 are Result Voltages Vi and M = 88.2. Volks. V2 = 21:15 Volts
