What resistance reading would you expect between two points in a circuit when there is an open circuit?

When measuring resistance in an open circuit, you would expect the resistance reading to show infinity or open loop (OL) on a digital multimeter. This is because an open circuit indicates that there is a break in the conductive path, preventing any current from flowing between the two points being measured.

In electrical terms, when trying to pass current through an open circuit, there is no complete path for the current to travel, resulting in an infinitely high resistance. Therefore, the multimeter is unable to detect any continuity or pathway for current flow, and it displays a reading that indicates an open circuit condition, which is represented as infinity or OL.

Other resistance readings, such as 0 ohms or specific values like 200 ohms or 100 ohms, would suggest that there is a closed circuit allowing for current passage through those two points. However, in an open circuit situation, those values cannot apply since they denote continuity rather than the lack of it.
