voltage - Electrical Engineering Stack Exchange

You are right about open circuit, the wires are disconnected. In case of short circuit as well as closed circuit, the wires ARE connected but the difference is that in case of short circuit, the resistance between the connection is extremely low so very high current flows as per ohm's law, whereas in case of close circuit, the connection offers considerable resistance, hence no high current issue.

Open-circuit voltage - Wikipedia

Open-circuit voltage (abbreviated as OCV or V OC) is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals. Alternatively, the open-circuit voltage may be thought of as the voltage that must be applied to a solar cell or a battery to stop the current.

Open Circuit and Short Circuit - Ultimate Electronics Book

Open and short circuit provide two useful points on the V-I curve. In particular: The open circuit voltage is the voltage difference measured between two terminals when no current is drawn or supplied. The short circuit current is the current that flows when the terminals are forced to have zero voltage difference.
