1. Basic knowledge of measurements, measurement methods, errors, and unit systems can be explained and classified.
2. Able to understand the operating principle of the indicator, explain current / voltage measurement, and select an accurate indicator.
3. Able to explain the measurement principle of resistance and impedance.
4. Able to understand the measurement principle of electric power and electric energy, and explain the oscilloscope waveform measurement method.
Outline:
Understanding the basic theory of electrical measurement, indicator instruments, and methods of measuring various electrical quantities are the basic requirements for an electrical engineer. Through this lecture, the purpose is to acquire the basic theory and necessary knowledge and methods related to electrical and electronic measurement.
Style:
Classes will be centered on lectures, but we will also learn from each other in pairs and groups. Tasks will be given to confirm the degree of understanding.
Notice:
What you learned in basic electrical subjects such as electrical circuits and electromagnetism is applied to measuring instruments. I would like you to understand the basic theory of electrical systems and the measurement principle in relation to each other, not by rote memorization.
