5-1 In each of the three cases shown in the figure, find the equivalent resistance 4 pts between points A and B. R = 3.41e3, R2 = 5490, and R3 (a) R, Rz R A-WWB (b)(c) = 8290. B , B R www R3 (a) Equivalent resistance between A and B in figure (a). (+ 20 ) (b) Equivalent resistance between A and B in figure (b). (+ 20 ) (c) Equivalent resistance between A and B in figure (c). ( 20 )
