A uniform metallic wire of lenght L is mounted in two configurations. In configuration I (triangle), it is an equilateral triangle and a voltage V is applied to corners A and B. In configuration 2 (circle), it is bent in the form of a circle, and the potential v is applied at diameterically opposite points P and Q. The ratio of the power dissipated in configuration 1 to configuration 2 is.
A. `2//3`
B. `9//8`
C. `5//4`
D. `7//8`
