We measure the values by ammeter and voltmeter in this experiment. If we use ideal meters, we can ignore the meters own resistance. But we use real meters which are not ideal. These actual meters extract energy from the system while making measurements. A real ammeter has an equivalent resistance that is not zero, and it thus effectively adds resistance to the circuit in series with the resistor whose current the ammeter is reading. A real voltmeter has an equivalent resistance that is not infinite, so it effectively adds resistance to the circuit in parallel with the resisor whose voltage is being read. 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 기초, 실험, 연세, 전기, 연세대학교, 차
