Open circuit voltage (or potential) is voltage which is not connected to any load in a circuit. See the two examples below to see the difference between open circuit voltage with a voltage source which is in a closed circuit and connected to a load. As you can see, open circuit voltage is disconnected and does not form a complete circuit.

An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a "closed circuit". If there's a break anywhere in the circuit, you have an open circuit, and current can not flow. In an open circuit, the two terminals are disconnected.

1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).
