Question

In the figure R₁ = 120 Ω, R₂ = R₃ = 43.0 Ω, R₄ = 106 Ω, and the ideal battery has emf ε = 6.00 V. (a) What is the equivalent resistance? What is i in (b) resistance 1, (c) resistance 2, (d) resistance 3, and (e) resistance 4?

R RA + 18 R2 RS

Answer 1

a) Pin 22 R2 is R₂, Rz & Ry are parallel YR = 743 + 1/43 + /186 R' <ly Ry 'V2 = 17-8952 Req=R, +R'= 137.8952 6V = 0.0435A, Y = i R, = 5-22 V req 137.89 V=6-5.22 = 0.778V 2 =0.018 A b) i = lunent in Ry © in V2 R2 d) {z = V₂ R3 ya V2 = 0.018 A e) 0.007 A Ry
