Which of the following is the proper way to study the sinusoidal waveform of voltage?
Correct answer: A. Voltage is connected to 'Y' input and time base is switched on
- A. Voltage is connected to 'Y' input and time base is switched on
- B. Voltage is connected to 'X' input and time base is switched off
- C. Voltage is connected to 'Y' input and time base is switched off
- D. Voltage is connected to 'X' input and time base is switched on
Explanation
If an AC voltage is applied across the Y-plates when the timebase is on then the sinusoidally varying voltage makes the spot move up and down around its rest position as it moves across the screen and you see a sine wave graph.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
