What is the resistance between points C and E?

0 ohms
Measurable resistance
Infinity
100 ohms

The correct answer is: Infinity

The resistance between points C and E is considered to be infinity, which implies that there is an open circuit between these two points. This situation typically occurs in electrical circuits when there is a break in conductive path or when the components connected between the two points do not allow current flow. In practical terms, if you were to measure resistance with a multimeter across points C and E and found that it reads infinite resistance, it would indicate that no current can flow between those points, demonstrating that they are not electrically connected in any way. Thus, the concept of infinite resistance aptly describes an open circuit scenario where the potential difference does not allow current, leading to no measurable resistance.
