Ideal diodes act as perfect conductor and perfect insulator. Practical diodes cannot act as perfect conductor and perfect insulator. Ideal diode draws no current when reverse biased. Practical diode draws very low current when reverse biased.

Hey Friend!
Here's your answer:
An ideal diode is a theoretical concept that assumes the diode behaves perfectly. It conducts current in one direction (forward bias) with zero resistance, allowing current to flow freely. In the opposite direction (reverse bias), it blocks the flow of current completely, acting as an open circuit.
On the other hand, a practical diode is a real-world diode that exhibits some non-ideal characteristics. It has a small forward voltage drop and a finite reverse leakage current, even in reverse bias. It may not provide perfect conduction or blocking of current, but it still functions as a one-way valve for electrical current.
In summary, an ideal diode is an idealized model with perfect behavior, while a practical diode is a real-world device with some non-ideal characteristics.
Hope that helped you!
