Electrical Network - Electrical Laws

Electrical Laws

A number of electrical laws apply to all electrical networks. These include:

  • Kirchhoff's current law: The sum of all currents entering a node is equal to the sum of all currents leaving the node.
  • Kirchhoff's voltage law: The directed sum of the electrical potential differences around a loop must be zero.
  • Ohm's law: The voltage across a resistor is equal to the product of the resistance and the current flowing through it.
  • Norton's theorem: Any network of voltage or current sources and resistors is electrically equivalent to an ideal current source in parallel with a single resistor.
  • Thévenin's theorem: Any network of voltage or current sources and resistors is electrically equivalent to a single voltage source in series with a single resistor.

Famous quotes containing the words electrical and/or laws:

    Few speeches which have produced an electrical effect on an audience can bear the colourless photography of a printed record.
    Archibald Philip Primrose, 5th Earl Rosebery (1847–1929)

    It is the manners and spirit of a people which preserves a republic in vigour. A degeneracy in these is a canker which soon eats to the heart of its laws and constitution.
    Thomas Jefferson (1743–1826)
