Explain the measurement of voltage and frequency using CRO.

1 Answer

Answer :

Voltage Measurement: CRO displays the voltage signal as a function of time on its screen. The amplitude of that voltage signal is constant, but we can vary the number of divisions that cover the voltage signal in vertical direction by varying volt/division knob on the CRO panel. Therefore, we will get the amplitude of the signal, which is present on the screen of CRO by using following formula.

A=j×nv

Where,

A is the amplitude

j is the value of volt/division

nv is the number of divisions that cover the signal in vertical direction.
