본문 EXERCISES Section 25.1 Circuits, Symbols, and Electromotive Force 14. A literal reading of the circuit specifications results in connections like those in sketch (a). Because the connecting wires are assumed to have no resistance (a real wire is represented by a separate resistor), a topologically equivalent circuit diagram is shown in sketch (b). 15. INTERPRET This problem is about how various circuit elements can be connected to form a closed series circuit. DEVELOP In a series circuit, the same current must flow through all elements. EVALUATE One possibility is shown below. The order of elements and the polarity of the battery connections are not specified. ASSESS An important feature about a series circuit is that the current through all the components must be the same. With two batteries, the direction of the current flow is determined by the polarity of the larger of the two voltage ratings. 16. The circuit has three parallel branches: one with and in series; one with just and one with the battery (an ideal emf in series with the internal resistance). 17. INTERPRET This problem explores the connection between the emf of a battery and the energy it delivers. DEVELOP Electromotive force, or emf, is defined as work per unit charge, EVALUATE Substituting the values given in the problem statement, we find the emf to be 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 단원, 핵심, 레포트답안, 전기파트, 핵심물리학, 물리학
