Unformatted text preview: 26.10: a) The three resistors R2 , R3 and R4 are in parallel, so: R234 1 1 1 1 1 1 = R + R + R = 8.20 Ω + 1.50 Ω + 4.50 Ω 3 4 2 ⇒ Req = R1 + R234 = 3.50 Ω + 0.99 Ω = 4.49 Ω . −1 −1 = 0.99 Ω b)  I1 = ε 6.0 V = = 1.34 A ⇒ V1 = I1R1 = (1.34 A) (3.50 Ω) = 4.69 V. Req 4.49 Ω VR234 R2 = 1.33 V = 0.162 A, 8.20 Ω ⇒ VR234 = I1 R234 = (1.34 A) (0.99 Ω) = 1.33 V ⇒ I 2 = I3 = VR234 R3 = VR 1.33 V 1.33 V = 0.887 A and I 4 = 234 = = 0.296 A. 1.50 Ω R4 4.50 Ω ...
