When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state ; in simple terms, it is the possibility of a risk-free profit at zero cost.

According to the theorem, it is possible to expand the power ( x + y )< sup > n </ sup > into a sum involving terms of the form ax < sup > b </ sup > y < sup > c </ sup >, where the exponents b and c are nonnegative integers with, and the coefficient a of each term is a specific positive integer depending on n and b. When an exponent is zero, the corresponding power is usually omitted from the term.

When investors and managers perform DCF analysis, the important thing is that the net present value of the decision after discounting all future cash flows at least be positive ( more than zero ).

When the cell is being charged, the anode becomes the positive (+) and the cathode the negative (−) electrode.

When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.

When considering the band structure and binding energy of a metal, it is necessary to take into account the positive potential caused by the specific arrangement of the ion cores – which is periodic in crystals.

When and are either both positive or both negative, then can also be thought of as asserting that both and have the same remainder.

When the voltage of C1 right-hand plate ( Q2 base voltage ) becomes positive and reaches 0. 6 V, Q2 base-emitter junction begins diverting a part of R2 charging current.

When they encounter an infection site the particles gain a positive charge provoked by the slightly acidic environment at the infection sites, allowing them to bind to the negatively charged bacterial cell walls and release antibiotics at locally high concentration.

When the odds of drawing a card that wins the pot are numerically higher than the pot odds, the call has a positive expectation ; on average, you win a portion of the pot that is greater than the cost of the call.

When a ( positive ) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles.

When V is positive, electrons in the tip tunnel into empty states in the sample ; for a negative bias, electrons tunnel out of occupied states in the sample into the tip.

When the system is used for physical three-space, it is customary to use positive sign for azimuth angles that are measured in the counter-clockwise sense from the reference direction on the reference plane, as seen from the zenith side of the plane.

When measured as a function of mean solar time rather than uniform time, the effect appears as a positive acceleration.

When the band's first album, Sorry Ma, Forgot to Take Out the Trash, finally appeared in August 1981, it received positive reviews in local fanzines.

Reviews for When Harry Met Sally ... were mostly positive.

When we feel kindness and love and with this attitude do good things, which are beneficial to both ourselves and others, this is positive action.

When the reaction is exothermic ( ΔH is negative, puts energy out ), we include heat as a product, and, when the reaction is endothermic ( ΔH is positive, takes energy in ), we include it as a reactant.

When Φ is 2-positive, a stronger assumption than merely positive, one has something that looks very similar to the original Cauchy – Schwarz inequality:

When ΔV < sub > cell </ sub > is positive, then positive electrical charge flows through the cell from the left electrode ( anode ) to the right electrode ( cathode ).

When the system is idle, the CPU clocks itself down via lower bus multiplier and selects a lower voltage.

When a program demands more computational resources, the CPU quickly ( there is some latency ) returns to an intermediate or maximum speed with appropriate voltage to meet the demand.

When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor.

When the voltage rises above the normal range, the diodes become forward-biased ( conducting ).

When the current changes, the magnetic field does too, inducing a voltage between the ends of the conductor.

When faced with a new circuit, the software first tries to find a steady state solution, that is, one where all nodes conform to Kirchhoff's Current Law and the voltages across and through each element of the circuit conform to the voltage / current equations governing that element.

When calculating the difference in voltage, one must first manipulate the half-cell reactions to obtain a balanced oxidation-reduction equation.

When the current flowing through an inductor changes, creating a time-varying magnetic field inside the coil, a voltage is induced, according to Faraday's law of electromagnetic induction, which by Lenz's law opposes the change in current that created it.

When there is a sinusoidal alternating current ( AC ) through an inductor, a sinusoidal voltage is induced.

When subjected to a high enough voltage, insulators suffer from the phenomenon of electrical breakdown.

When no voltage is applied to a TN liquid crystal cell, polarized light passes through the 90-degrees twisted LC layer.

When no voltage is applied, the liquid crystals remain perpendicular to the substrate creating a black display between crossed polarizers.

When voltage is applied, the liquid crystals shift to a tilted position allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field.

When the jar is charged with a high voltage and carefully dismantled, it is discovered that all the parts may be freely handled without discharging the jar.

When the coil is energized with direct current, a diode is often placed across the coil to dissipate the energy from the collapsing magnetic field at deactivation, which would otherwise generate a voltage spike dangerous to semiconductor circuit components.

When a conducting tip is brought very near to the surface to be examined, a bias ( voltage difference ) applied between the two can allow electrons to tunnel through the vacuum between them.

When a small bias V is applied to the system, only electronic states very near the Fermi level, within eV ( a product of electron charge and voltage, not to be confused here with electronvolt unit ), are excited.

( When there is no exchange, telephones often have hand-cranked magnetos to make the ringing voltage.

When a voltage is applied to the primary winding, a small current flows, driving flux around the magnetic circuit of the core.

When the wedge was pushed down onto the surface of a crystal and voltage applied to the other side ( on the base of the crystal ), current started to flow from one contact to the other as the base voltage pushed the electrons away from the base towards the other side near the contacts.

When a voltage is applied between the gate and body terminals, the electric field generated penetrates through the oxide and creates an " inversion layer " or " channel " at the semiconductor-insulator interface.
