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 all the operating variables were varied simultaneously, Af operations would be required to do the same job, and as R increases this increases very much more rapidly than the number of operations required by the dynamic program.

If we define the function f ( n ) = A ( n, n ), which increases both m and n at the same time, we have a function of one variable that dwarfs every primitive recursive function, including very fast-growing functions such as the exponential function, the factorial function, multi-and superfactorial functions, and even functions defined using Knuth's up-arrow notation ( except when the indexed up-arrow is used ).

If the current account is in surplus, the country's net international asset position increases correspondingly.

If production of one good increases along the curve, production of the other good decreases, an inverse relationship.

If the frequency deviation is held constant and the modulation frequency increased, the spacing between spectra increases.

If a larger fire is necessary, the smith increases the air flowing into the fire as well as feeding and deepening the coke heart.

If water is evaporated too quickly, the membrane dries, resistance across it increases, and eventually it will crack, creating a gas " short circuit " where hydrogen and oxygen combine directly, generating heat that will damage the fuel cell.

If the political situation stabilizes, high crime levels wane, and new investment increases, tourism could take its place next to export-oriented manufacturing ( the assembly sector ) as a potential source of foreign exchange.

If the position angle of the body's Prime Meridian increases with time, the body has a direct ( or prograde ) rotation ; otherwise the rotation is said to be retrograde.

If a higher minimum wage increases the wage rates of unskilled workers above the level that would be established by market forces, the quantity of unskilled workers employed will fall.

If a company increases prices too much, then others may enter the market if they are able to provide the same good, or a substitute, at a lesser price.

If the coil is designed to be energized with alternating current ( AC ), a small copper " shading ring " can be crimped to the end of the solenoid, creating a small out-of-phase current which increases the minimum pull on the armature during the AC cycle.

If the separation is decreased by 1 Ǻ, the current increases by an order of magnitude, and vice versa.

" If Deaf people learn to read and write in their own signing system, that increases their self-esteem ", says Dianne Parkhurst.

# If demand increases and supply remains unchanged, then it leads to higher equilibrium price and higher quantity

# If demand remains unchanged and supply increases, then it leads to lower equilibrium price and higher quantity.

If ' is positive, the resistance increases with increasing temperature, and the device is called a positive temperature coefficient ( PTC ) thermistor, or posistor.

If, as observed in most cases, a substance is more dense in the solid than in the liquid state, the melting point will increase with increases in pressure.

If the payment involves the issue of new shares, it is similar to a stock split in that it increases the total number of shares while lowering the price of each share without changing the market capitalization, or total value, of the shares held.

If desmopressin reduces urine output and increases osmolarity, the pituitary production of ADH is deficient, and the kidney responds normally.

If HDI increases, there is higher rate of human capital formation in response to higher standard of education and health.

Lebesgue presents six conditions which it is desirable that the integral should satisfy, the last of which is " If the sequence f < sub > n </ sub >( x ) increases to the limit f ( x ), the integral of f < sub > n </ sub >( x ) tends to the integral of f ( x ).

If a safe pharmacological treatment can be developed – one that increases expression of lysosomal sialidase in neurons without other toxicity – then this new form of therapy could essentially cure the disease.

If these are not insulated, this increases the energy requirements of a process, and therefore the cost and environmental impact.
