# Potentials Sentence Examples

- Take any horizontal line and divide it into small elements of length each representing dq, and draw vertical lines representing the
**potentials**v, v', &c., and after each dose. - If the quadrants of an electrometer are con - nected to the ends of a non-inductive circuit in series with the power-absorbing circuit, and if the needle is connected to the end of this last circuit opposite to that at which the inductionless re - sistance is connected, then the deflexion of the electrometer will be proportional to the power taken up in the circuit, since it is pro - portional to the mean value of (A - B) IC - 1 (A ±B)}, where A and B are the
**potentials**of the quadrants and C is that of the needle. - In any case, therefore, in which we can sum up the elementary
**potentials**at any point we can calculate the resultant electric force at the same point. - Let V 1 and V2 be the
**potentials**of the plates, and let a charge Q be given to one of them. - It depends on the principle that if two condensers of capacity C I and C2 are respectively charged to
**potentials**V I and V2, and then joined in parallel with terminals of opposite charge together, the resulting potential difference of the two condensers will be V, such that V = (C,V 2 -CiV2) /(C1+C2) (16); and hence if V is zero we have C I: C2 = V2 The method is carried out by charging the two condensers to be compared at the two sections of a high resistance joining the ends of a battery which is divided into two parts by a movable contact.' - Electrostatic voltmeters are based on the principle that when two conductors are at different
**potentials**they attract one another with a force which varies as the square of the potential difference (P. D.) between them. - The chemical
**potentials**are clearly functions of the composition of the system, and of its temperature and pressure. - The
**potentials**that have to be dealt with are often hundreds and sometimes thousands of volts, and insulation troubles are more serious than is generally appreciated. - Observations on mountain tops generally show high
**potentials**near the ground. - For since electricity tends to move between points or conductors at different
**potentials**, if the electricity is at rest on them the potential must be everywhere the same. - Electromagnetic voltmeters may therefore be thermal, electromagnetic or electrodynamic. As a rule, electromagnetic voltmeters are only suitable for the measurement of relatively small
**potentials**- o to 200 or 300 volts. - This measurement is applicable to the measurement of high
**potentials**, either alternating or continuous, provided that in the case of alternating currents the high resistance employed is wound non-inductively and an electrostatic voltmeter is used. - A saturated solution is a system in equilibrium, and exhibits the thermodynamic relations which hold for all such systems. Just as two electrified bodies are in equilibrium when their electric
**potentials**are equal, so two parts of a chemical and physical system are in equilibrium when there is equality between the chemical**potentials**of each component present in the two parts. - It is usual to call each part of the system of uniform composition throughout a phase; in the example given, water substance, the only component is present in two phases - a liquid phase and a vapour phase, and when the
**potentials**of the component are the same in each phase equilibrium exists. - To determine these variables we may form equations between the chemical
**potentials**of the different components - quantities which are functions of the variables to be determined. - If µ i and µ2 denote the
**potentials**of any one component in two phases in contact, when there is equilibrium, we know that µ i =P2 If a third phase is in equilibrium with the other two we have also =123. - After the discharge was once started, the difference of
**potentials**at the terminals of the tube varied from 630 volts upwards. - In the theory of surfaces, in hydrokinetics, heat-conduction,
**potentials**, &c., we constantly meet with what is called " Laplace's operator," viz. - Volta made use of such an electroscope in his celebrated experiments (1790-1800) to prove that metals placed in contact with one another are brought to different
**potentials**, in other words to prove the existence of so-called contact electricity. - Suppose it is required to measure the difference of
**potentials**V and V' of two conductors. - If W is the weight required to depress the attracted disk into the same sighted position when the plates are unelectrified and g is the acceleration of gravity, then the difference of
**potentials**of the conductors tested is expressed by the formula V - V'=(d - d') /87 W where S denotes the area of the attracted disk. - The difference of
**potentials**is thus determined in terms of a weight, an area and a distance, in absolute C.G.S. - If the two quadrants are at different
**potentials**, the needle moves from one quadrant towards the other, and the image of a spot of light on the scale is therefore displaced. - According to the mathematical theory of the instrument,' if V and V' are the
**potentials**of the quadrants and v is the potential of the needle, then the torque acting upon the needle to cause rotation is given by the expression, C(V - V'){v-2(V-{-V')}, where C is some constant. - If v is very large compared with the mean value of the
**potentials**of the two quadrants, as it usually is, then the above expression indicates that the couple varies as the difference of the**potentials**between the quadrants. - In the same way it may be employed to measure high
**potentials**by measuring the fall of potential down a fraction of a known non-inductive resistance. - Instead of calculating the direction and magnitude of the resultant force on each particle arising from the action of neighbouring particles, he formed a single expression which is the aggregate of all the
**potentials**arising from the mutual action between pairs of particles.
