If enough electricity is provided by solar panels, wind turbines, or other means, then electric heaters and stoves become a practical autonomous design.

If enough electric power is available, cooling can be provided by conventional air conditioning using a heat pump.

where Q is the electric charge transferred through the surface over a time t. If Q and t are measured in coulombs and seconds respectively, I is in amperes.

If only the electric field () is non-zero, and is constant in time, the field is said to be an electrostatic field.

If used in a permanent installation, a split sensor allows the electric current to be tested without dismantling the existing circuit.

If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance.

If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force

If they did exist, both Gauss's law for magnetism and Faraday's law would need to be modified, and the resulting four equations would be fully symmetric under the interchange of electric and magnetic fields ; see magnetic monopoles for details.

If plasma is pushed hard enough, it generates electric fields which allow it to move in response to the push, often ( not always ) deforming the magnetic field in the process.

If the user opens the protective sliding door that covers the pins, the processor can be exposed to any electric charge the user has built up.

If the dipole moment can be reversed by the application of an electric field, the material is said to be ferroelectric.

If the sunspot were isolated from the surrounding photosphere it would be brighter than an electric arc.

If the appliance is one whose purpose is for light or heat ( such as an incandescent lightbulb or electric oven ) then the lighting or heating elements may be considered as a type of fire ; if so, then turning them on constitutes both " lighting a fire " ( category 37 ) and " cooking " ( a form of baking, category 11 ), and turning them off would be " extinguishing a fire " ( category 36 ).

If this condition is met, the input electric power must equal the output power:

If the components of the computer were too large or the wires interconnecting them too long, the electric signals couldn't travel fast enough through the circuit, thus making the computer too slow to be effective.

If an electric boat has sails as well, and will be used in deep water ( deeper than about 15 m or 50 ft ), then a towed generator can help build up battery charge while sailing ( there is no point in trailing such a generator while under electric propulsion as the extra drag from the generator would waste more electricity than it generates ).

If the wave is frozen in time, the electric field vector of the wave describes a helix along the direction of propagation.

If the applied electric field is sufficiently high, free electrons from background radiation may become accelerated to velocities that can liberate additional electrons during collisions with neutral atoms or molecules in a process called avalanche breakdown.

If more than one charge is present, the total electric field at any point is equal to the vector sum of the separate electric fields that each point charge would create in the absence of the others.

If several spatially distributed charges generate such an electric potential, e. g. in a solid, an electric field gradient may also be defined.

If this susceptibility itself depends upon the electric field, one can obtain a nonlinear optical effect of magneto-optical parametric generation ( somewhat analogous to a Pockels effect whose strength is controlled by the applied magnetic field ).

If one considers the flux of the electric field vector, E, for a tube near a point charge in the field the charge but not containing it with sides formed by lines tangent to the field, the flux for the sides is zero and there is an equal and opposite flux at both ends of the tube.

If it comes down too hard on the potential dangers of fallout, it will box the President on resuming atmospheric tests.

If Af is the change per unit volume in Gibbs function caused by the shear field at constant P and T, and **yr is the density of the fluid, then the total potential energy of the system above the reference height is Af.

If such is the case, the particles within a distance of about Af of the Earth will have, relative to the Earth, a kinetic energy less than their potential energy and they will be captured into orbits about the Earth.

If this precaution was not taken, the potential customers would be at the mercy of " 2 sets of carob seeds ".

If there is a change in the potential energy of a system ; for example μ < sub > 1 </ sub >> μ < sub > 2 </ sub > ( μ is Chemical potential ) an energy flow will occur from S < sub > 1 </ sub > to S < sub > 2 </ sub >, because nature always prefers low energy and maximum entropy.

To avoid debates about the possibility of in-vitro fertilization, artificial insemination, or cloning, the original Darwin Awards book applied the following " deserted island " test to potential winners: If the person were unable to reproduce when stranded on a deserted island with a fertile member of the opposite sex, he or she would be considered sterile.

If the second electrode is also at standard conditions, then the measured cell potential is called the standard electrode potential for the electrode.

If the electrode has a positive potential with respect to the SHE, then that means it is a strongly reducing electrode which forces the SHE to be the anode ( an example is Cu in aqueous CuSO < sub > 4 </ sub > with a standard electrode potential of 0. 337 V ).

If the current is driven in the opposite direction by imposing an external potential, then work is done on the cell to drive electrolysis.

If the observer is at a lower gravitational potential than the source, a gravitational blueshift can be observed instead.

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 we live on a brane ( as hypothesized by some theorists ) this " leakage " of gravitons from the brane into higher-dimensional space could explain why gravitation is such a weak force, and gravitons from other branes adjacent to our own could provide a potential explanation for dark matter.

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 a philosophy of Becoming is not possible without change, then ( the potential of ) what is to become must already exist in the present object.

If, however ,... potential suicide murderers ... will refrain from killing out of fear that their mothers will become homeless, it would be immoral to leave the Palestinian mothers untouched in their homes while Israeli children die on their school buses.

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 net excitation received by a neuron over a short period of time is large enough, the neuron generates a brief pulse called an action potential, which originates at the soma and propagates rapidly along the axon, activating synapses onto other neurons as it goes.

If the change in electrical potential is large enough, it evokes an action potential, which is transmitted along the axon of the receptor cell, into the spinal cord.

If the top has mass and its center of mass is at a distance from the pivot point, its gravitational potential is

If the work done moving along a path which starts and ends in the same location is zero, then the force is said to be conservative and it is possible to define a numerical value of potential associated with every point in space.

If the potential is redefined at A to be and the potential at B to be, where is a constant ( i. e. can be any number, positive or negative, but it must be the same at A as it is at B ) then the work done going from A to B is
