Answer 1

3t6 Ans. 1. Ry and Ry are in series, equivalent resistance of Ry and R3 is given by a R34 = RytR3 - Sts R3y = 6 kr Now Ray and R2 are in paralles, there equivalent scrutance is given by a RowRe Rezu - Rzx R34 - 3x6 =18 R₂ + R34 R234 = 2 ke Now, R and Rq34 are in series, there or overall equivalent resistance of circuit is z) Ri23y = RitRq3y R1234 = 2+2 R1234 = 4 kat = 4 x 10t3r Current through whole circuit will be a I = VI - 12 . R1234 4x10 +3 I 3 Ampere I = 3x10-3 Ampere Voltage across R is an VRI - IXR, 342.

same VR = 3x10-3x (2x103) VRI = 60 Now voltage across Ro or Ry and Rp is since, they are in paralles. given by ) VRR = VRBRY - VI-VRI VRIRY = 12-6 VRIRY = 60 Current through Ry and Rg will be =) Isu = VRARY – Exio Ž Isu = 103 Ampere voltage across R3 u a) Vez - Igy XR3 VR2 = 10-3x (1x103) VR - IV
