Unformatted text preview: 1 1 1 + + 26.54: a) Req (8, 16, 16) = 8 16 16 = 4.0 ; 1 1 Req (9, 18) = + 9 18 = 6.0 . So the circuit is equivalent to the one shown below. Thus: 1 1 Req = 6 + 6 + 20 + 4 = 8.0 -1 -1 -1 b)If the current through the 8 - resistor is 2.4 A, then the top branch current is I (8, 16, 16) = 2.4 A + 1 2.4 A + 1 2.4 A = 4.8 A. But the bottom branch current is twice 2 2 that of the top, since its resistance is half. Therefore the potential of point a relative to point x is Vax = - IReq (9, 18) = - (9.6 A) (6.00 ) = - 58 V. ...
