A sinusoidal waveform, when observed on an oscilloscope, has a peak to peak amplitude of 4 cm. If the vertical sensitivity setting is 7.5 V/cm, the rms value of the voltage is__ (in V)
    Correct answer is between '10.5,10.7'. Can you explain this answer?
    Verified Answer
    A sinusoidal waveform, when observed on an oscilloscope, has a peak to...
    Vertical voltage sensitivity = 7.5 V/cm
    Peak to peak voltage = 7.5 × 4 = 30 V
    Maximum voltage = 15 V
    Rms value of the voltage = 15/√2 = 10.6 V

    Given Data:
    - Peak to peak amplitude = 4 cm
    - Vertical sensitivity setting = 7.5 V/cm

    Calculating Peak Amplitude:
    - Peak amplitude = Peak to peak amplitude / 2
    - Peak amplitude = 4 cm / 2 = 2 cm

    Converting Peak Amplitude to Voltage:
    - 1 cm on the oscilloscope corresponds to 7.5 V
    - Peak amplitude in voltage = Peak amplitude in cm * Vertical sensitivity setting
    - Peak amplitude in voltage = 2 cm * 7.5 V/cm = 15 V

    Calculating RMS Value:
    - For a sinusoidal waveform, RMS value is given by: RMS = Peak / √2
    - RMS value = 15 V / √2 ≈ 10.61 V

    Therefore, the RMS value of the voltage is approximately 10.61 V, which falls within the range of 10.5 V to 10.7 V as per the correct answer provided.
