Question

Choose the correct waveform that can represent the voltage across $R$ of the following circuit, assuming the diode is ideal one:

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

When $V_i>3$ volt, $V_R>0$
Because diode will be in forward biased state
When $V_i\le 3$ volt $;V_R=0$
Because diode will be in reverse biased state
