Open-circuit voltage
Definition of open-circuit voltage. The box is any two-terminal device, such as a battery or solar cell. The two terminals are not connected to anything (an open circuit), so no current can flow into or out of either terminal. The voltage v oc between the terminals is the open-circuit voltage of the device.
