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.

“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)
“So far as laws and institutions avail, men should have equality of opportunity for happiness; that is, of education, wealth, power. These make happiness secure. An equal diffusion of happiness so far as laws and institutions avail.”
—Rutherford Birchard Hayes (1822–1893)
