Refer to Figure P2.64 and determine the equivalent resistance between terminals a and b if terminal c is wired (shorted) to terminal a and terminal d is wired (shorted) to terminal b.





What will be an ideal response?


Known quantities:
Schematic of the circuit shown in Figure P2.64.
Find:
The equivalent resistance seen by terminals a and b.
Analysis:
Shorting a to c eliminates the 360? resistor. Shorting b to d eliminates the rightmost 540? resistor. This leaves the remaining two resistors in parallel with each other.

540?||180?=R_eq
R_eq=135?
