I don't normally do electricity questions unless they're really easy
can someone tell me whether the centre "diamond" is supposed to have zero resistance, because if it is, why don't the right-hand sides of the "diamond" short-out the four right-hand resistances?

An equivalent resistance problem is a type of circuit problem where the goal is to find a single resistance value that can replace a complex circuit with multiple resistors. This simplifies the circuit and makes it easier to analyze.
The equivalent resistance can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current. In a series circuit, the equivalent resistance is the sum of all individual resistances. In a parallel circuit, the equivalent resistance is calculated using the formula 1/R = 1/R1 + 1/R2 + ... + 1/Rn.
Finding the equivalent resistance allows us to simplify complex circuits and make them easier to analyze. It also helps us understand the behavior of the overall circuit and how changing the resistance values may affect the circuit's performance.
There are a few key principles to keep in mind when solving an equivalent resistance problem. These include understanding the difference between series and parallel circuits, knowing how to calculate equivalent resistance for each type of circuit, and being familiar with Ohm's Law and its applications.
Some useful tips for solving equivalent resistance problems include breaking down complex circuits into smaller, simpler parts, using diagrams or drawings to visualize the circuit, and double-checking your calculations to ensure accuracy. It may also be helpful to practice solving various types of equivalent resistance problems to become more familiar with the concepts and formulas.
