🤓 Based on our data, we think this question is relevant for Professor Li's class at FIU.

You are given a copper bar of dimensions 3 cm x 5 cm x 8 cm and asked to attach leads to it in order to make a resistor. If you want to achieve the SMALLEST possible resistance, you should attach the leads to the opposite faces that measure

(a) 3 cm x 8 cm.

(b) 5 cm x 8 cm.

(c) 3 cm x 5 cm.

(d) Any pair of faces produces the same resistance.
