If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

If the data to be compressed is analog ( such as a voltage that varies with time ),

If a chemical reaction is driven by an external applied voltage, as in electrolysis, or if a voltage is created by a chemical reaction as in a battery, it is an electrochemical reaction.

If drain-to-source voltage is increased, this creates a significant asymmetrical change in the shape of the channel due to a gradient of voltage potential from source to drain.

If drain-to-source voltage is increased further, the pinch-off point of the channel begins to move away from the drain towards the source.

If the magnetic field is applied by a solenoid, the sensor output is proportional to the product of the current through the solenoid and the sensor voltage.

If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer.

If the answer was incorrect, the teacher would administer a shock to the learner, with the voltage increasing in 15-volt increments for each wrong answer.

If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives.

If the inverting input is held at ground ( 0 V ) directly or by a resistor, and the input voltage V < sub > in </ sub > applied to the non-inverting input is positive, the output will be maximum positive ; if V < sub > in </ sub > is negative, the output will be maximum negative.

If predictable operation is desired, negative feedback is used, by applying a portion of the output voltage to the inverting input.

If the input voltages change in the same direction, the negative feedback makes Q3 / Q4 base voltage follow ( with 2V < sub > BE </ sub > below ) the input voltage variations.

If the base current to the transistor is assumed to be zero, the negative feedback forces the transistor to increase its collector-emitter voltage up to 1 V until its base-emitter voltage reaches 0. 625 V ( a typical value for a BJT in the active region ).

If the voltage to be sensed, E < sub > i </ sub >, is applied to op amp's (+) input, the result is a noninverting positive-level detector: when E < sub > i </ sub > is above V < sub > ref </ sub >, V < sub > O </ sub > equals + V < sub > sat </ sub >; when E < sub > i </ sub > is below V < sub > ref </ sub >, V < sub > O </ sub > equals − V < sub > sat </ sub >.

If the component is a resistor with time-invariant voltage to current ratio, then:

If the voltage is zero, this means that the resistance is zero.

If the collector voltage were zero, the collector current would be limited only by the light bulb resistance and the supply voltage.

If a load is connected to the secondary winding, the load current and voltage will be in the directions indicated, given the primary current and voltage in the directions indicated ( each will be alternating current in practice ).

If a mutual is large, or is expected to grow if it can raise capital by a conversion, its managers derive more value from a conversion but do not suffer much loss of perks than if the bank were small.

If a sheet is for multiple days it shows a conversion table to convert from weekday to date and back.

If they make what would normally be a field goal, they score one point ; what would normally be a touchdown scores two points ( a " two-point conversion ").

If the team scores a touchdown, starting with the 2010 season, it is required to attempt a 2-point conversion.

If this view is correct, the epistle should be dated somewhere around 47, depending on other difficult to date events, such as Paul's conversion.

If the DNA is to be used after separation on the agarose gel, it is best to avoid exposure to UV light by using a blue light excitation source such as the XcitaBlue UV to blue light conversion screen from Bio-Rad or Dark Reader from Clare Chemicals.

If mature potatoes are refrigerated, dark spots can occur and conversion of starch into sugar can give rise to an unpleasant sweet flavour when cooked.

If after twelve months ' probation he perseveres, he may promise before the whole community stabilitate sua et conversatione morum suorum et oboedientia -- " stability, conversion of manners, and obedience ".

If an image stored in one vector file format is converted to another file format that supports all the primitive objects used in that particular image, then the conversion can be lossless.

If a preamplifier has been used prior to A / D conversion, the noise introduced by the amplifier can be an important contributing factor towards the overall SNR.

Following his conversion to Christianity, C. S. Lewis believed that the resurrection of Jesus belonged in this category of myths, with the additional property of having actually happened: " If God chooses to be mythopoeic — and is not the sky itself a myth — shall we refuse to be mythopathic?

If the choice of input data type is not under the control of the programmer, although prior conversion ( outside of a loop for instance ) to a faster data type carries some overhead, it can often be worthwhile if the variable is then to be used as a loop counter, especially if the count could be quite a high value or there are many input values to process.

If a third party transfers possession of property to an employee for delivery to his employer, the employee has possession of the property and his conversion of the property would be embezzlement rather than larceny.

If a quarter ends as a touchdown is scored, an untimed conversion attempt takes place.

If a waiting period is required ( such as for analog-to-digital conversion ), then the master must wait for at least that period of time before starting to issue clock cycles.

If the two positions are originally given as latitudes and longitudes, a conversion to n-vectors must first be performed.

If an attacker reaches it first their team scores a ' rouge ', worth five points and also attempts a conversion ( see below ).

If the input value was permitted to change during this comparison process, the resulting conversion would be inaccurate and possibly completely unrelated to the true input value.

If R1 and R2 ( note equation at top of page ) are different substituents, the conversion of the enol to the keto tautomer affords enantiomers.

If the person who is converting is male, circumcision is a part of the traditional conversion process as well.

If the price of fuel remains constant but the efficiency of its conversion into work is doubled, the effective price of work is halved and twice as much work can be purchased for the same amount of money.

If friction, absorption, electrical resistance or a similar energy conversion takes place that releases heat, the impact of that heat on thermodynamic potentials must be considered, and it is this impact that decreases the available energy.

:" If we can accept as absolutely necessary the conversion of Haweswater < nowiki > a reservoir </ nowiki >, then it must be conceded that Manchester have done the job as unobtrusively as possible.

If no other tests ( either bacteriologic culture or more specific serology ) are available, a fourfold increase in the titer ( e. g., from 1: 40 to 1: 160 ) in the course of the infection, or a conversion from an IgM reaction to an IgG reaction of at least the same titer, would be consistent with a typhoid infection.
