Response Details:
In the diagram given that diode is ideal one.
That is when the diode is ON it acts as short-circuit and if it is OFF it acts as open circuit.
 
(1)
In this case the diode is acts as open circuit when is less than .
Current
The diode acts as short-circuit when is greated than .
When the diode is in ON state equation for current
 
Plot for this case:
