  2. Ohm's law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_law

    Ohm's law has been observed on a wide range of length scales. In the early 20th century, it was thought that Ohm's law would fail at the atomic scale, but experiments have not borne out this expectation. As of 2012, researchers have demonstrated that Ohm's law works for silicon wires as small as four atoms wide and one atom high. [17]

  3. Electrical network - Wikipedia

    en.wikipedia.org/wiki/Electrical_network

    A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...

  4. Supply creates its own demand - Wikipedia

    en.wikipedia.org/wiki/Supply_creates_its_own_demand

    Supply creates its own demand" is a formulation of Say's law. The rejection of this doctrine is a central component of The General Theory of Employment, Interest and Money (1936) and a central tenet of Keynesian economics. See Principle of effective demand, which is an affirmative form of the negation of Say's law.

  5. Electricity - Wikipedia

    en.wikipedia.org/wiki/Electricity

    Ohm's law is a basic law of circuit theory, stating that the current passing through a resistance is directly proportional to the potential difference across it. The resistance of most materials is relatively constant over a range of temperatures and currents; materials under these conditions are known as 'ohmic'.

  6. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...

  7. Law of supply - Wikipedia

    en.wikipedia.org/wiki/Law_of_supply

    A supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...

  8. Drude model - Wikipedia

    en.wikipedia.org/wiki/Drude_model

    Basically, Ohm's law was well established and stated that the current J and voltage V driving the current are related to the resistance R of the material. The inverse of the resistance is known as the conductance.

  9. Léon Charles Thévenin - Wikipedia

    As a result of studying Kirchhoff's circuit laws and Ohm's law, he developed his famous theorem, Thévenin's theorem, [1] which made it possible to calculate currents in more complex electrical circuits and allowing people to reduce complex circuits into simpler circuits called Thévenin's equivalent circuits.
