The currents are not necessarily in the direction shown. (assume r1 = 17.0 ω, r2 = 7.0 ω, and v = 18 v.) (a) find the current in each resistor of the figure above by using the rules for resistors in series and parallel. 7.0 ω a 17.0 ω a 24 ω a (b) write three independent equations for the three currents using kirchoff's laws: one with the node rule; a second using the loop rule through the battery, the 7.0-ω resistor, and the 24.0-ω resistor; and the third using the loop rule through the 17.0-ω and 24.0-ω resistors. solve to check the answers found in part (a). (do this on paper. your instructor may ask you to turn in this work.)
