What should you expect in terms of resistance in an open circuit?

In an open circuit, there is a break or disconnection in the path of current flow, meaning that electric current cannot travel through the circuit. Because the circuit is not complete, the resistance is considered to be infinite. This is based on Ohm's Law, which states that resistance is equal to voltage divided by current (R = V/I). Since the current (I) is zero in an open circuit, the calculation leads to the conclusion that resistance must be infinitely large, reflecting the inability of current to flow at all.

In practical terms, this infinite resistance indicates that the circuit is completely non-conductive due to its open condition. Understanding this concept is crucial for diagnosing issues in electrical systems, as it helps technicians determine whether a circuit is functioning correctly or if a break exists that needs to be addressed.
