Each side of square ABCD (A is connected to B and D) represents resistance of 1 Ohm.
What is resistance between:
a) A and B
b) A and C

Hmmmmmm?

A. 3\4

B. 1

There is no resistance between them because they are connected without using a restrictive path or square where all ends freely touch. The question didn't ask the resistance from A through C or from A through B.



Your question therefor is a trick...

The answer is 0 Ohm

In this question we want to know total resistance of the circuit
created by four resistors connected such way that they form a square
with four corners: A, B, C and D.
Ryan and Wolfe got it right. Now you can go to question #6

Bahhhhhh



I understand the concept of each side of the square being .25 Ohms and the whole being 1 Ohm starting at A and ending with back to A.

So much for my english degree! :D

(A is connected to B and D) represents resistance of 1 Ohm

If you add C to the equation, wouldn't the total resistance be 1.333?



a) A and B 1/2
b) A and C 3/4

I’ve used this statement to avoid possible confusion in assigning
letters to corners of the square.
