### What is Open Circuit Voltage

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.
