What is the resistance between points A and C?

  1. 0 ohms

  2. Measurable resistance

  3. Infinity

  4. 10 ohms

The correct answer is: 0 ohms

The resistance between points A and C being 0 ohms suggests that there is a direct electrical connection between these two points with no obstacles to the flow of current. This scenario can occur in ideal situations, such as in a perfect conductor where there is no resistive material present in the path. In practical terms, this means that if one were to measure the resistance across these points, the measurement would indicate that current flows freely, akin to a short circuit. This outcome is significant in circuits because a resistance of 0 ohms implies no energy is lost in the form of heat, making the connection very efficient for conducting electricity. Understanding this concept is crucial when analyzing electrical circuits, especially when diagnosing issues or designing new systems. The idea of "0 ohms" indicates that all potential barriers to current flow are effectively bypassed at this juncture.
