If the password is carried as electrical signals on unsecured physical wiring between the user access point and the central system controlling the password database, it is subject to snooping by wiretapping methods.

If a band of allowable energies is completely filled by electrons, it cannot carry any electrical current, because that would require the electron's energy to be increased.

If a load is connected to the secondary winding, current will flow in this winding, and electrical energy will be transferred from the primary circuit through the transformer to the load.

If the secondary coil is attached to a load that allows current to flow, electrical power is transmitted from the primary circuit to the secondary circuit.

If the thermistor is being used to measure the temperature of the environment, this electrical heating may introduce a significant error if a correction is not made.

If electrical power fails, the ballast is released, and the submarine then ascends to safety.

If the NEP refers to the signal power absorbed in the detector, it is known as the electrical NEP.

If a purely resistive load is connected to a power supply, current and voltage will change polarity in step, the power factor will be unity ( 1 ), and the electrical energy flows in a single direction across the network in each cycle.

If the current J is alternating because the applied voltage or E-field varies in time, then reactance must be added to resistance to account for self-inductance, see electrical impedance.

If only a certain portion of the electrical power received from the transmitter is actually radiated by the antenna ( its efficiency ) the directive gain compares the power radiated in a given direction to that reduced power, ignoring the inefficiency.

If the APU or its electrical generator is not available, the aircraft cannot be released for ETOPS flight and is forced to take a longer non-ETOPS route.

If a micrometeorite of about 10 µm impacted, it would fracture the wire, destroy the electrical connection, and thus record the event.

If the electrical stress is high enough, nitrogen oxides ( NOx ) can form.

If the surface had been liquid, other sensors would also have measured its density, temperature, thermal conductivity, heat capacity, electrical properties ( permittivity and conductivity ) and refractive index ( using a critical angle refractometer ).

If an electric field is applied to a material, and the resulting induced electric current is in the same direction, the material is said to be an isotropic electrical conductor.

If the resulting electric current is in a different direction from the applied electric field, the material is said to be an anisotropic electrical conductor.

If the pores are partially filled with gas or oil, which are resistant to the passage of electrical current, the bulk formation resistance is higher than for water filled pores.

If a quantity of charge − de is acquired by a system at an electrical potential Ψ, the electrical work associated with this is − Ψde, which would be included in the infinitesimal expression.

If the black hole rotates, and the image of the pellet is pulled around, the associated electrical fieldlines ought to be pulled around with it to create basic " electrical dynamo " effects ( see: dynamo theory ).

If this current limiting was eliminated, the flash tube would attempt to draw high currents from the electricity source, potentially tripping electrical breakers or causing voltage drops in the power supply line.

If these rivers were to be damned it could provide at least five million kilowatts of the total electrical needs ( some 56 %) of the entire country, but would displace entire populations, drowning their houses and rice terraces, covering existing roads, and ending complete cultures.

If the drift error is systematic, it can be canceled with a bias circuit which can be arranged and adjusted to supply the required compensating current.

If the traffic on a virtual circuit is exceeding its traffic contract, as determined by the GCRA, the network can either drop the cells or mark the Cell Loss Priority ( CLP ) bit ( to identify a cell as potentially redundant ).

If a user added more than one drive to a system the user had to open the case and cut a trace in the circuit board to permanently change the drive's number, or hand-wire an external switch to allow it to be changed externally.

If the sources are constant ( DC ) sources, the result is a DC circuit.

If high output powers are needed from a class-A circuit, the power waste ( and the accompanying heat ) will become significant.

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

If repeated application of the input pulse maintains the circuit in the unstable state, it is called a retriggerable monostable.

If further trigger pulses do not affect the period, the circuit is a non-retriggerable multivibrator.

If E < sub > i </ sub > is applied to the inverting input, the circuit is an inverting positive-level detector: When E < sub > i </ sub > is above V < sub > ref </ sub >, V < sub > O </ sub > equals − V < sub > sat </ sub >.

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 the Grade of Service is calculated based on the number of calls rejected by the final circuit group, then the Grade of Service is determined by the final circuit group blocking criteria.

If the power supply and ground wires have significant resistance, the voltage drop across them may create noise voltage pulses in the ground wires, which are applied to other parts of the circuit, The large capacitance of the ground plane allows it to absorb the current pulses without much change in voltage,

If done sufficiently quickly, the receiving devices will not detect that some of the circuit time was used to serve another logical communication path.

If a squelch circuit is operating, the receiver attack-time delay includes the time for the receiver to break squelch.

If the total allowable REN load is exceeded, the phone circuit may fail to ring or otherwise malfunction.

If a mole of ions goes into solution ( for example, in a Daniell cell, as discussed below ) the charge through the external circuit is:

If the light bulb is removed ( open circuit ) the emf between the electrodes is opposed by the electric field due to charge separation, and the reactions stop.

If parasitic effects are significant, point-to-point wiring has the disadvantage compared to a PCB of indeterminate parasitic components ; while the inductance and capacitance due to a PCB are the same for all samples, values may vary between point-to-point wired units, changing circuit operation.

If the resistance of the load is made larger than the resistance of the source, then efficiency is higher, since a higher percentage of the source power is transferred to the load, but the magnitude of the load power is lower since the total circuit resistance goes up.

If we define the efficiency as the ratio of power dissipated by the load to power developed by the source, then it is straightforward to calculate from the above circuit diagram that
