Question
Assuming the ideal diode, draw the output waveform for the circuit given in Fig. Explain the waveform.

Answer

An ideal diode behaves like a perfect conductor when voltage is applied forward biased and like a perfect insulator when voltage is applied reverse biased.
When input voltage is greater than 5V, diode is conducting
When input is less than 5V, diode is open

The current in a conductor and the potential difference across its ends are measured by an ammeter and a voltmeter. The meters draw negligible currents. The ammeter is accurate but the voltmeter has a zero error (that is, it does not read zero when no potential difference is applied). Calculate the zero error if the readings for two different conditions are 1.75A, 14.4V and 2.75A, 22.4V.
