Ohm, Georg Simon (1787-1854) German physicist, who taught in Cologne, Berlin, Nuremberg, and finally (1849) Munich. He is best known for formulating Ohm s law in 1827. The unit of electrical resistance is named after him. [Pg.578]

The Voltaie battery eoneeived and built toward the end of 1799 in Como, was the first deviee to produee a steady flow of eleetrieity, or eleetrie eurrent. The instrument enabled other natural philosophers, notably Humphry Davy, to develop eleetroehemistry as a new braneh of seienee, and still others, notably Hans Christian Oersted and Georg Simon Ohm, to explore eleetromagnetism. Beeause of these later developments—showing that ehemieal, eleetrieal... [Pg.1205]

German physicist George Simon Ohm publishes Die galvmische kette, mathematisch hcaihcitct, in which he describes his discovery that the voltage across an electrical conductor is proportional to the electrical current, and that the current is inversely proportional to the resistance of the conductor. [Pg.1244]

The phenomenological equation for electrical conduction is Ohm s law, which first appeared in Die galvanische kette mathematisch bearbeitet (the galvanic circuit investigated mathematically), the 1827 treatise on the theory of electricity by the Bavarian mathematician Georg Simon Ohm (1789-1854). Ohm discovered that the current through most materials is directly proportional to the potential difference apphed across the... [Pg.254]

Ohm s law is a relationship between the voltage across an electric circuit, the electrical resistance in the circuit, and the current in the circuit. This law is named after its discoverer, Georg Simon Ohm. Ohm found that for most electric circuits, the voltage across the circuit was equal to the current flowing through the circuit times the electrical resistance of the circuit. For the same voltage, a circuit with a low resistance will... [Pg.642]

Georg Simon Ohm, a German physicist, discovered a relationship among voltage, current, and resistance-Voltage equals the product of the current and the resistance - (Ohm s law). [Pg.301]

Ohms law (I = E/R) was originally published with an additive constant term (/ = E/R + C). Ohm spent the rest of his life trying to amend his original mistake. If you were George Simon Ohm, how would you go about doing this ... [Pg.27]

In the nineteenth century, a German physicist named Georg Simon Ohm discovered that there is a directly proportional relationship between the voltage, resistance, and current flow in an electrical system. This mathematical relationship is called Ohm s law. Ohm s law states that voltage = current X resistance (E = IX R). Engineers use the diagram in Figure 13-28 to visually demonstrate Ohm s law. [Pg.282]

The ohm is the SI unit of resistance of an electrical conductor. Its symbol is the capital Greek letter omega . It is named after the German physicist Georg Simon Ohm (1789-1854). [Pg.333]

The potential difference (p.d.) is the change in energy levels measured across the load terminals. This is also called the volt drop or terminal voltage, since e.m.f. and p.d. are both measured in volts. Resistance in every circuit offers some opposition to current flow, which we call the circuit resistance, measured in ohms (symbol O), to commemorate the famous German physicist Georg Simon Ohm, who was responsible for the analysis of electrical circuits. [Pg.64]

Georg Simon Ohm (Erlangen, 16 March 1789-Munich, 6 July 1854), the son of a locksmith, entered the University of Erlangen at the age of sixteen but... [Pg.136]

Ohm om, [Georg Simon Ohn (1867) (Q) n. The SI unit of electrical resistance, equal to IV divided by 1 A. The SI definition for 1Q is the resistance between two points of a conductor when a constant difference of potential of 1V, apphed between these two points, produce in this conductor a current of 1 A, this conductor not being the source of any electromotive force. [Pg.672]

Georg Simon Ohm (1789-1854) German physicist Cologne and Munich, Germany. [Pg.3]

Experiments by Georg Simon Ohm indicated that all musical tones arise from simple harmonic vibrations of definite frequency, with the constituent components determining the sound quality. This gave birth to the field of musical acoustics. Helmholtz s studies of instruments and Rayleigh s work contributed to the nascent area of musical acoustics. Helmholtz s knowledge of ear physiology shaped the field that was to become physiological acoustics. [Pg.3]

Ohm s Law. The basis of electrical measurement is found in Ohm s law, derived by Georg Simon Ohm in the nineteenth century. According to Ohm s law, the current flowing in an electric circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. In other words, the greater the volume applied to the circuit, the more current will flow. Conversely, the greater... [Pg.578]

Henry Cavendish discovered what would he known as Ohm s law about fifty years earlier than Georg Simon Ohm did. However, as Cavendish did not publish his observations, the law has been attributed to Ohm. [Pg.579]

Ohm The unit of electric resistance through which one ampere of current will flow when there is a difference of one volt. The quantity is named for the German physicist Georg Simon Ohm (1787-1854). [Pg.2503]

The unit of electrical resistance, the ohm, is named after Georg Simon Ohm (1787-1854), a German physicist who discovered the law that bears his name. Ohms Taw states that the potential difference (in volts) measured in an electrical circuit equals the product of the current (in amperes) times the resistance (in ohms). [Pg.116]
