Circuit equation

...(1) means that the potential corresponding to the elevation of the road network can be considered, and (2) means that no current is generated or lost. The current paths connecting the nodes are called branches, and by formulating and solving circuit equations for the current of each branch and the potential of each node, the voltage and current of each part of the circuit can be obtained. To formulate a circuit equation, the relationship between the current i flowing through each branch and the voltage v (the difference between the nodal potentials at both ends) must be known, but in the case of a linear circuit, this can be expressed as a combination of six constants: voltage E of the voltage source, current I of the current source, resistance R = v / i , capacitance C = i /( dv / dt ), inductance L = v /( di / dt ), and mutual inductance between branch 1 and branch 2. ...

…(1)は道路網の標高に対応するような電位が考えられることを意味し，(2)は電流の発生や消滅がないことを意味している。節点どうしを結ぶ電流の通路を枝といい，各枝の電流，各節点の電位に関し，回路方程式をたてて解くと，回路各部の電圧，電流が求められる。　回路方程式をたてるには，各枝に流れる電流iと電圧v(両端の節点電位の差)との関係がわからなければならないが，線形回路の場合は電圧源の電圧E，電流源の電流I，抵抗R＝v/i，キャパシタンスC＝i/(dv/dt)，インダクタンスL＝v/(di/dt)，枝1と枝2との間の相互インダクタンスの6個の定数の組合せで表現できる。…
