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)
“I would have these good people to recollect, that the laws of this country hold out to foreigners an offer of all that liberty of the press which Americans enjoy, and that, if this liberty be abridged, by whatever means it may be done, the laws and the constitution, and all together, is a mere cheat; a snare to catch the credulous and enthusiastic of every other nation; a downright imposition on the world.”
—William Cobbett (1762–1835)
