Here, the question asks me to work out the resistance between X and Y. The answer is 1.2 ohms.
In a normal circuit, the resistance between two points is simply whatever resistor value(s) is between the two points (and parallel circuit rules apply). So by this reasoning, why can't I say that the resistance between X and Y is 2 ohms, since there is ONLY a 2 ohms resistor between X and Y? I've seen these square resistors circuits before and they tend to confuse me, so how do they work, and how do I calculate the resistance between X and Y?
