The semiconductor diodes.
The characteristics of an ideal diode are those of a switch that can conduct current in only one direction.

In general, it
is relatively simple to determine whether a diode is in the region of
conduction or non-conduction simply by noting the direction of the current ID established by an applied voltage. For conventional flow (opposite to that of electron flow) , if the resultant diode current has the same direction as the arrowhead of the diode symbol, the diode is operating in the conducting region as depicted.
Redrawing the network as shown in Fig. 2.33 reveals that the resulting current direction is such as to turn on diode D1 and turn off diode D2. The resulting current I is then.
