Vi Graph For Diode. Has a very high resistance in one direction. In the beginning the current changes very quickly for a small change in voltage and reaches the saturation current.
An Ideal diode also acts as a switch. If a potential difference is applied across a diode in the direction with low resistance it is said to be forward bias. It will then increase.
A diode A diode only allows current to flow in one direction through it forward biased when the current tries to flow the other way reverse biased no current is allowed to flow through the diode.
