① Describe the electrical parameters that we can measure using oscilloscope.
Oscilloscope is a device that can measure the voltage signal that varies of time. Thus, we can obtain waveform of voltage basically. Plus, measurement tool included in oscilloscope helps us to get the more precise data, such as magnitude of voltage(Vp-p, Vavg, Vrms), frequency and period of wave, and phase/time differences of two wave signals.(We can guess the parameter values by observing the waveform, but it is not exact compared with measure tool of oscilloscope)
② What are the errors that can be generated during measuring voltage with oscilloscope?
Since experiment is not ideal, values may not match exactly compared with theoretical values. That can make errors. These are detailed reasons.
- We assumed that wire has no resistance in experiment, but wire has a little resistance.
- Oscilloscope is not ideal device, and it express the measured values as calculating down to two places of decimals. Thus measured value is differ from theoretical value.
- The values are shaken up and down, thus the values we measured maybe not exact.
- The way oscilloscope get the value is measuring waveform that appear on monitor, thus it can measure the spark-on wave(error) value as the Vp-p value.
