  2. 노드(Node) : 회로상에서 연결점 Super nod : 하나이상의 노드를 포함하는 영역을 정의 함으로써 얻어진다. 기준 노드(refrence node) : 보통 가장 많은 가지(branch)가 결합되어 있는 마디 가지 (Branch) - 마디와 마디 간의 연결 - 회로상에서 가지의 수는 회로 소자의 수와 같음 Branch

  3. Node Voltage method 노드전압법: In electric circuits analysis, nodal analysis, node-voltage analysis, or the branch current method is a method of determining the voltage (potential difference) between "nodes" (points where elements or branches connect) in an electrical circuit in terms of the branch currents. Node A KCL 적용 Node B 참고 :http://ee.hawaii.edu/~eyoung/EE211/NVM/nvm3.html

  4. Node Voltage method 참고 :http://www.ktword.co.kr/abbr_view.php?id=194&m_temp1=4543&nav=2

  5. 루프(Loop) A loop is any closed path in a circuit. Loop counts starting at a node passing through a set of nodes and returning to the starting node without passing through any node more than once. A network with b branches, n nodes and l independent loops will satisfy the fundamental theorem of network topology, b = l + n – 1 참고 :http://www.engineersblogsite.com/what-is-node-branch-and-loop-in-a-circuit.html

  6. 루프 해석법, 망로해석법(LoopAnalysis) 참고 :http://www.ktword.co.kr/abbr_view.php?id=194&m_temp1=4543&nav=2

  7. 메시(Mesh) * 다른 루프를 포함하지 않는 루프

  8. Mesh Current method 방법 및 절차 망전류(mesh current) 정의: 일관된 방향(시계방향) 망전류를이용하여 각 전압 표시 & KVL 적용 선형연립방정식 수립 참고 : http://en.wikipedia.org/wiki/Mesh_analysis

  9. Mesh Current method Super mesh A supermesh occurs when a current source is contained between two essential meshes. The circuit is first treated as if the current source is not there. This leads to one equation that incorporates two mesh currents. Mesh current method video : http://www.youtube.com/watch?v=jUOu7WvI_7Y 참고 : http://en.wikipedia.org/wiki/Mesh_analysis

  10. Thevenin 등가회로 두 단자를 가진 임의의 회로망을 하나의 등가전원과 하나의 등가저항이 직렬 연결된 회로로 바꾸어 놓을 수 있다는 것

  11. Thevenin 등가회로 흐르는 전류 전압 Thevenintheorm video : http://www.youtube.com/watch?v=rwHgicnjJEE 참조 : http://electrical4u.com/thevenin-theorem-and-thevenin-equivalent-voltage-and-resistance/

  12. Norton 등가회로

  13. Norton 등가회로 Norton Equivalent Circuit Norton 등가회로에서의 등가저항 RN의 값은 Thevenin등가회로의 등가저항 Rth의 값과 같고, 따라서 Rth와 같은 방법으로 구할 수 있다. 참조 : http://electrical4u.com/norton-theorem-norton-equivalent-current-and-resistance/

  14. 중첩의 원리(Superposition principle) Step – 1 Replace all but one of the sources by their internal resistances. Step – 2 Determine the currents in various branches using simple Ohm’s law . Step – 3 Repeat the process using each of the sources turn – by turn as the sole source each time. Step – 4 Add all the currents in a particular branch due to each source. This is the desired value of current at that branch when all the sources acting on the circuit simultaneously. 참조 : http://electrical4u.com/superposition-theorem/

  15. 회로의 선형성(Linearity) 두 신호 사이에는 어떤 연관관계도 발생하지 않는다. 참고 : http://www.rfdh.com/bas_rf/begin/linear.htm
