In an open circuit:

Explanation:
An open circuit means there is a break in the conducting path so the loop isn’t completed. Because there’s no closed path, current has no route to follow, so it cannot flow—even when a voltage source is connected. The voltage can still exist across the gap, but the current is effectively zero since the path’s resistance is infinite at the break. This aligns with I = V/R: with the path broken, current cannot pass. The other statements imply a closed loop or active current flow, which isn’t the case in an open circuit.
