Module 6: AC Measurements

Dear Studnets
  1. Refer to the multimeter reading shown in the figure below and answer the questions:
    a. Is the multimeter displaying the rms voltage or the peak voltage?
    _____________________________________________________
    b. What is the peak voltage?
    _____________________________________________________
  2. If the frequency set on the function generator = 500 Hz and if the oscilloscope reading gives 550 Hz, calculate the percent error in frequency.

    AC Measurments
    1) a. Displaying the rms voltage
    b. Peak Voltage = rms Voltage / 0.707 = 5.85 V
    2) Percentage error = (|500-550|/ 500) x 100 = 10%

    1) 4.14 V
    2) 4.14 * 0.707= 0.926 V

    3) Percentage error = (|500-550|/ 500) x 100 = 10%

    Q1- Displaying the rms voltage

    Q2- Peak Voltage is the maximum value reached by an ac wave. Vp = Vrms / 0.707 =
    4.14 / 0.707 = 5.85 V

    Q3- Percentage error = (|500-550|/ 500) x 100 = 10%

    Q2. The peak voltage is the maximum value reached by an AC wave:
    Vp = Vrms / 0.707
    Vp = 4.14 / 0.707 = 5.85v

    Q3. The Percentage error = (|True value-Measured value| / True value) x 100
    The percentage error = (|500-550| / 500) x 100
    = 10%
