Final answer:
An ideal diode is considered to have a small forward voltage drop across the junction, allowing current to flow freely in the forward-bias configuration.
Step-by-step explanation:
An ideal diode is considered to have a small forward voltage drop across the junction. This statement is true.
In the forward-bias configuration, when the anode of the diode is positive and the cathode is negative, the diode allows current to flow freely. As the voltage applied increases, the current through the diode increases, but the voltage across the diode remains approximately 0.7 V. This small forward voltage drop allows the diode to conduct current in only one direction.
For example, if the forward voltage drop across the diode is 0.7 V and the voltage across the diode is 1 V, the voltage across the load connected in series with the diode would be approximately 0.3 V.
