The resistance for the network shown in Figure P2.20 between terminals a and b with copen circuited is Rab=50 Ω. Similarly, the resistance between terminals b and c with a open is Rbc=100 Ω,and between c and a with b open is Rca=70 Ω. Now, suppose that a short circuit isconnected from terminal b to terminal c, and determine the resistance between terminal a andthe shorted terminals b–c.
