Abstract

The purpose of this experiment is to learn about the basic equipment for analyzing electric systems, then measure the resistance with these tools, and lastly analyze the RLC circuit system. In general, the mechanical system and electric system show the same form of 2nd order ODE, which means that it is important to understand the relationship between the mechanical and electric system.
Here, resistance measurement experiment and function generator & oscilloscope experiment are conducted. First, 3 different types of resistors are used, which are 220 Ω, 1,000 Ω, and 10,000 Ω. With these resistors, 3 single-resistor circuit and 3 complex circuits are constructed and the resistance can be measured. Compared to theoretical resistance, it shows error rate of 0.00%, 0.60%, 0.30%, 0.18%, 2.00%, 0.63% for each experiment. It mostly shows less error than the margin of error of the resistors, and the cause of error is mainly from the resistance of other equipment or the insufficiency of times of experiment.

Methods

Resistance Measurement Experiment
1. 220Ω, 1kΩ, 10kΩ 저항을 color code를 확인하여 준비한다.
2. NI myDAQ를 작동시킨 뒤, 브레드보드에 각 단일 저항을 연결하여 회로를 구성하고 도선을 연결한다.
3. NI ELVISmx 프로그램의 Digital Multimeter(DMM)의 저항 측정 기능을 실행하고, 각 저항의 크기를 측정한다.
4. Table 3의 구성에 따라 회로를 직렬, 병렬, 혼합 연결한 뒤 등가 저항을 측정한다.
5. 측정된 값과 이론적으로 계산된 값을 비교한다.
