Semiconductor Electronics/Diode/Ideal Diode
An Ideal diode has the following characteristics. Practical realization of ideal diode is an impossibility because of physical limitations. However an ideal diode makes the student to grasp about diode concepts in a quick and crisp manner.
Zero Forward Resistance
[edit | edit source]An ideal diode has zero forward resistance. This means if current passes through a diode, it produces no heat loss. In other words an ideal diode in its forward bias acts like a closed switch in a electrical circuit.
