devre şeması

• aşağıdaki kanunlar bu devre şemalarına esas olarak uygulanır.
  kirchhoff akım kanunu: the sum of all currents entering a node is equal to the sum of all currents leaving the node.
  kirchhoff voltaj kanunu: the directed sum of the electrical potential differences around a circuit must be zero.
  ohm kanunu: the voltage across a resistor is the product of its resistance and the current flowing through it.
  the y-delta transform
  norton teoremi: any two-terminal collection of voltage sources and resistors is electrically equivalent to an ideal current source in parallel with a single resistor.
  thevenin teoremi: any two-terminal combination of voltage sources and resistors is electrically equivalent to a single voltage source in series with a single resistor.
  millman metodu: the voltage on the ends of branches in parallel is equal to the sum of the currents flowing in every branch divided by the total equivalent conductance.
