In the circuit containing an ideal PN diode D and a resistor R is given an input square wave as shown.
Understand the Problem
The question is about a circuit involving an ideal PN diode and a resistor given an input square wave. It seems to require analysis related to the behavior of the circuit with respect to the square wave input.
Answer
Positive half cycles of the input square wave.
The output waveform across the resistor R will be a series of positive half cycles corresponding to the positive halves of the input square wave, while the output will be zero during the negative halves of the input square wave.
Answer for screen readers
The output waveform across the resistor R will be a series of positive half cycles corresponding to the positive halves of the input square wave, while the output will be zero during the negative halves of the input square wave.
More Information
An ideal diode will block all current when reverse biased and allow full current flow when forward biased, causing the output across R to reflect only the positive halves of the input square wave.
Tips
Common mistakes include assuming the diode allows current in both directions or that the output waveform mirrors the input waveform.
