Question

(a) Find the current in each resistor of the figure above by using the rules for resistors in series and parallel.

(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 3.0 resistor, and the 24.0 resistor; and the third using the loop rule through the15.0 and 24.0 resistors. (Do this on paper. Your instructor may ask you to turn in this work.) Solve to check the answers found in part (a).

Explanation / Answer

(15*24/(15+24)9.231 for the parallel circuit + 3 for the series circuit

Req12.231 ==>39 V/12.231 3.19 A total in circuit==>3 *3.19 A9.57 V

39-9.57=29.43 V across the parallel circuit==>29.43/151.96 A

29.43/241.23 A==>

a) amps for R33.19 A==>amps for R151.96 A==>amps for R241.23 A

b) look above
