Cathode-Ray Oscilloscope

A cathode-ray oscilloscope is a laboratory instrument used to:

Display, measure, and analyze waveforms of electrical circuits

The a.c. current on a cathode-ray oscilloscope is represented as a:

Transverse wave

The cathode-ray oscilloscope can be used to determine:

The frequency and amplitude of the a.c. current

The d.c. voltage on a cathode-ray oscilloscope is represented as a:

Horizontal line at the relevant voltage

The x-axis of a cathode-ray oscilloscope is:

Time

The y-axis of a cathode-ray oscilloscope is:

Voltage or y-gain

Draw a cathode-ray oscilloscope display and label the time base and wavelengths:

On a cathode-ray oscilloscope, the period of the wave can be determined from the:

Time base

On a cathode-ray oscilloscope, the time base is:

How many seconds each division represents

The time-base on a cathode-ray oscilloscope display is measured commonly in:

s/div or s/cm

How to obtain time period T from cathode-ray oscilloscope display?

Divide total time by number of wavelengths
