The knee voltage of a diode is approximately equal to the forward voltage.
The knee voltage is the voltage at which a diode starts to conduct current. It is also known as the threshold voltage or the turn-on voltage. The knee voltage is typically around 0.6 volts for silicon diodes and 0.7 volts for germanium diodes.
The applied voltage is the voltage that is applied across the diode. The barrier potential is the voltage that is required to overcome the depletion region at the junction of the two semiconductor materials in a diode. The breakdown voltage is the voltage at which a diode breaks down and conducts current in the reverse direction.
None of the other options are correct.
