A typical Cathode Ray Oscilloscope (CRO) is fundamentally designed to visually display and analyze which physical quantity with respect to time?
A. Magnetic Field
B. Voltage
C. Pressure
D. Temperature
Answer: Option B
Solution (By JKSSB Mock Tests)
A CRO uses an electron beam sweeping across a phosphorescent screen to create a visible graph. It is fundamentally a voltage-measuring instrument. The vertical deflection is directly proportional to the applied voltage, and the horizontal deflection is controlled by a time-base generator, allowing it to display voltage waveforms over time.
