The emfs in the figure below are &1 = 4.00 V and &2 = 18.0 V. The resistances are R1 = 17.0 0, R2 = 31.5 0, R3 = 47.5 0, and R4 = 58.0 0. Find the magnitude of the current in each resistor when the switch is in the following states. M RA R M + S R3 (a) open I1 = 0.1875 I2 = 0.1875 I3 = 0.1875 14 = 0 A (b) closed I1 = A 12 = A 13 = A IA = D Need Help? Read It Submit
