Introduction
The CRO may be used to measure electrical quantities like amplitude, time period, and frequency.
The CRO is used to measure various electrical quantities such as voltage, current, and frequency. The electron beam is directed at a phosphor-coated screen to produce a visual representation of the electrical signal. To measure a specific electrical quantity,
the CRO[1] is connected in parallel or series with the circuit under test and the voltage or current waveform is displayed on the screen. By analyzing the waveform, the CRO can provide accurate readings of various electrical quantities such as peak voltage, frequency, and duty cycle
