Practical Significance:
An alternating AC waveform varies in both magnitude and direction in more or less an even
manner concerning time. An AC function can mathematically represent either a power source or a single source with the shape of an AC waveform.
Procedure
1. Connect the function generator output to the CRO‟s channel using the CRO probe.
2. Adjust the volt per division and time per division of CRO such that the waveform of the
current or voltage can be observed properly.
3. Adjust the peak-to-peak value of the voltage
4. Measure and note down the period and peak value of the sine wave
5. Switch the supply
Observations:
- CART05Time period of AC waveform (T): 4 divisions
- Time per division: 2 μs/division
- Peak value of AC waveform: 6 divisions
- Volt per division: 0.5 V/division
Calculations :
- Time period of AC waveform (T): 4 divisions x 2 μs/division = 8 μs Seconds
- Peak value of AC waveform: 6 divisions x 0.5 V/division = 3 V volts
- RMS value of ac waveform = 3 V x 0.707 = 2.121 V Volts
- Average value of ac waveform = Peak value X 0.637 = 0 V
Result :
- Time period 8 μs seconds
- Peak value 3 volts
- R.M.S. value 2.121 volts
- Average value 0 volts
