# How to use *Ohm* in a sentence

The voltage on the left hand 10

**ohm**resistor is flowing out of the top terminal of the resistor.**Ohm**'s law, as it is called, was based upon an analogy with the flow of heat in a circuit, discussed by Fourier.To find the dc collector current, measure the dc voltage across the emitter resistor and use

**ohm**'s law.Features to choose from include 100

**ohm**and 1000**ohm**RTD and 2252**ohm**thermistor capabilities.His data for the thermal conductivity of various metals were for long the most trustworthy at the disposal of physicists, and his determination of the

**ohm**in terms of the specific resistance of mercury showed remarkable skill in quantitative research.AdvertisementIf we eliminate the reverse electromotive forces of polarization at the two electrodes, the conduction of electricity through electrolytes is found to conform to

**Ohm**'s law; that is, once the polarization is overcome, the current is proportional to the electromotive force applied to the bulk of the liquid.Ultimately the discrepancy was traced to an error which, not by Joule's fault, vitiated the determination by the electrical method, for it was found that the standard

**ohm**, as actually defined by the British Association committee and as used by him, was slightly smaller than was intended; when the necessary corrections were made the results of the two methods were almost precisely congruent, and thus the figure 772-55 was vindicated.An essential accompaniment therefore of the potentiometer is a series of standard low resistances, say of o 1, o oi, o ooi

**ohm**, and also a series of higher resistances divided into known fractions.Two styles, Livewire and

**Ohm**, are available with wire frames instead of grylamide.If you are in a spot where no one will hear you, saying "

**Ohm**" while breathing out sends sympathetic vibrations through your body which are naturally calming.AdvertisementTo pass a steady current in the direction opposite to this electromotive force of polarization, the applied electromotive force E must exceed that of polarization E', and the excess E - E' is the effective electromotive force of the circuit, the current being, in accordance with

**Ohm**'s law, proportional to the applied electromotive force and represented by (E - E')/ R, where R is a constant called the resistance of the circuit.But the ions of an electrolytic solution can move independently through the liquid, even when no current flows, as the consequences of

**Ohm**'s law indicate.In Germany the work of Martin

**Ohm**(System der Mathematik, 1822) marks a step forward.The standard

**ohm**, sub-standards up to 100,000 ohms, and below 1**ohm**to = 1/1000**ohm**.**Ohm**introduced the definite conception of the distribution along the circuit of " electroscopic force " or tension (Spannung), corresponding to the modern term potential.AdvertisementHe followed up the early work of the British Association Committee on electrical units by a fresh determination of the

**ohm**in absolute measure, and in conjunction with other work on the electrochemical equivalent of silver and the absolute electromotive force of the Clark cell may be said to have placed exact electrical measurement on a new basis.Another discussed conduction in curved sheets; a third the distribution of electricity in two influencing spheres; a fourth the deter mination of the constant on which depends the intensity of induced currents; while others were devoted to

**Ohm**'s law, the motion of electricity in submarine cables, induced magnetism, &c. In other papers, again, various miscellaneous topics were treated - the thermal conductivity of iron, crystalline reflection and refraction, certain propositions in the thermodynamics of solution and vaporization, &c. An important part of his work was contained in his Vorlesungen fiber mathematische Physik (1876), in which the principles of dynamics, as well as various special problems, were treated in a somewhat novel and original manner.One was a redetermination of the

**ohm**.This work, the germs of which had appeared during the two preceding years in the journals of Schweigger and Poggendorff, has exerted most important influence on the whole development of the theory and applications of current electricity, and

**Ohm**'s name has been incorporated in the terminology of electrical science.Nowadays "

**Ohm**'s Law," as it is called, in which all that is most valuable in the pamphlet is summarized, is as universally known as anything in physics.AdvertisementAn exactly similar assumption is made in the statement of

**Ohm**'s law, i.e.Clerk Maxwell and George Chrystal that

**Ohm**'s law is true, within the limits of experimental error, even when the currents are so powerful as almost to fuse the conducting wire.We conclude by applying

**Ohm**'s law that the electromotive force, E, of the thermocouple may be approximately represented for small differences of temperature by the formula E=CR=p(t-t').The dipole has a built-in transformer to match the 72

**ohm**balanced terminal impedance to 50**ohm**unbalanced (balun) feeder cable.For this purpose a resistance, say, of one

**ohm**is placed in series with the lamp and a resistance of 100,000 ohms placed across the terminals of the lamp; the latter resistance is divided into two parts, one consisting of loon ohms and the other of 99,000 ohms. The potentiometer enables us to measure therefore the current through the lamp by measuring the drop in volts down a resistance in series with it and the potential difference of the terminals of the lamp by measuring the drop in volts down the tooth part of the high resistance of 100,000 ohms connected across the terminals of the lamp.Advertisement**Ohm**in 1827, and since known as**Ohm**'s Law.**Ohm**(1787-1854) rendered a great service to electrical science by his mathematical investigation of the voltaic circuit, and publication of his paper, Die galvanische Kette mathematisch bearbeitet.**Ohm**introduced the clear idea of current strength as an effect produced by electromotive force acting as a cause in a circuit having resistance as its quality, and showed that the current was directly proportional to the electromotive force and inversely as the resistance.
