Find the potential difference across each resistor in the figure below. (R; = 5.15(Q, R, = 3.70 (), R; = 2.30 0, R, = 2.300Q) 12,0V 3.00V |18.0V Assume that the currents I,, I,, and I, are in the directions indicated by the arrows in the figure redrawn below. (Enter your answers to at least four significant figures.) 11 a 12 12.0 V 3.00 V 18.0 V R12 R23 R4 Rs Applying Kirchhoff's junction rule at a gives 13 = 11 + 12. [1] Using Kirchhoff's loop rule starting at point a and going clockwise around the leftmost loop yields -3.00 V - Ryl3 - RI, + 12.0 V = 0. Solving for I, gives 19 R R 1 or I1 = 1.75 X A) -( 0.718 x 13. [2]
