Question

Typically oscilloscope represents _____ .

• A. Current and time
• B. Resistance and time
• C. Voltage and time
• D. Power and time

Hint:

Oscilloscope Display. Standard mode displays Voltage (Y-axis) against Time (X-axis). Used to visualize and analyze time-varying electrical signals.

Answer 1

The Correct Option is C

An oscilloscope is an electronic test instrument that graphically displays varying signal voltages
The standard operating mode displays voltage on the vertical (Y) axis versus time on the horizontal (X) axis
The time base is generated internally, sweeping the electron beam horizontally at a constant rate
The input voltage signal deflects the beam vertically
This allows visualization of the waveform's amplitude, frequency, period, and shape over time
While current or other quantities can sometimes be displayed indirectly (e
g
, by measuring voltage across a known resistor for current), the fundamental display is Voltage versus Time
