  2. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). [5] [6] Current intensity is often referred to simply as current. [7] The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère's force law (1820). [8]

  3. Fluid theory of electricity - Wikipedia

    en.wikipedia.org/wiki/Fluid_theory_of_electricity

    Franklin's theory also provides the basis for conventional current, the thinking of electricity as being the movement of positive charges. Franklin arbitrarily thought of his electrical fluid as being of a positive charge, and therefore all thought was done in the frame of mind of a positive flow.

    Fleming's left-hand rule. Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule for generators. [1] [2] [3] They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.

    By historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current.

    The magnetic field (marked B, indicated by red field lines) around wire carrying an electric current (marked I) Compass and wire apparatus showing Ørsted's experiment (video [1]) In electromagnetism , Ørsted's law , also spelled Oersted's law , is the physical law stating that an electric current induces a magnetic field .

  8. Ohm's law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_law

    As seen in the figure, the current does not increase linearly with applied voltage for a diode. One can determine a value of current (I) for a given value of applied voltage (V) from the curve, but not from Ohm's law, since the value of "resistance" is not constant as a function of applied voltage. Further, the current only increases ...

  9. Talk:Coulomb - Wikipedia

    en.wikipedia.org/wiki/Talk:Coulomb

    Since the ampere per second is conventional current, would it technically be 6.24×10 18 times the charge on a proton? - Omegatron 16:36, May 26, 2004 (UTC) I think you're probably right. However, I think it probably also makes sense to say "1 coulomb of electrons", knowing that this is the same as -1 coulomb of conventional charge. -- Anon Er ...
