Question

In the figure, E = 127 V, R2 = 9.732, R2 = 18.1 2, R3 = 33.612, and L = 2.76 H. Immediately after switch S is closed, what are (a) i1 and (b) 12? (Let currents in the indicated directions have positive values and currents in the opposite directions have negative values.) A long time later, what are (c) 11 and (d) i2? The switch is then reopened. Just then, what are (e) 11 and (f) i2? A long time later, what are (9) 11 and (h) 2? R RS +8 (a) Number Units (b) Number Units UUUU (c) Number Units (d) Number Units (e) Number Units (f) Number Units (g) Number Units (h) Number Units

Answer 1

Immediately after swites R₂ = 33.6-2 R =9.732 7 E mm R2 = 18.1 2 1 ₂ 1278 I is closed L appose the wrrent flow so, all current flow through R2 E RitRL 127 (9.73+181) = 4.56A 4.56 A b 4.56A. A long time latter L will have no effect when steady current will of low R₂ & Ro in parallel with with R, in series { 127 5.91A 18.1833.6 9.73+ 18.1 +33.6 R2 + R₂ i, x R₂ R3 5-918 33.6 Ra 3.84A R₂ + R3 18-1533.6 R+ R₂ R3 1 2 5.91A d 3.84 A when switen is opened become equal to f -5.91-3.84 = 2.07 A and in become Zero tinal worrent through inductor

after Zero long time both arrent become - O A - оА
