Question

Refer to Figure 71.  Assume all values are in Ohms.  Given R1= 5, R2= 9,
        R3=14, R4=10, R5=16, R6=13, & R7= 3.
        Determine the equivalent Resistance (Req). Answer only.

Answer 1

Req = (R1+R2)//(R3+R4)}//R5+R6]//R7

=(14//24)//16}+13]//3

=8.84//16)+13}//3

=5.69+13)//3

= 18.69//3

=2.585 ohms
