The solenoid also closes high-current contacts for the starter motor, which begins to turn.

* The use of high-current fuses as ignitors can cause main circuit breakers and fuses to trip, due to the sudden inrush of hundreds of amperes through a dead-shorted circuit.

The line-frequency supply is usually a relatively simple design, but it becomes increasingly bulky and heavy for high-current equipment due to the need for large mains-frequency transformers and heat-sinked electronic regulation circuitry.

In the event that an abnormal high-current power draw is detected, the switched-mode supply can assume this is a direct short and will shut itself down before damage is done.

Alloyed aluminum wires are generally preferred to pure aluminum wire except in high-current devices because of greater drawing ease to fine sizes and higher pull-test strengths in finished devices.

An AC alternator is able to produce power across multiple high-current power generation coils connected in parallel, eliminating the need for the commutator.

Some RVs provide a momentary-on switch that flips a relay to form a temporary high-current connection between the two sets of batteries, enabling the driver to use the house batteries to help start the engine should the engine batteries prove weak.

Steep slope crossover filters are most effective at IMD reduction, but may be too expensive to implement using high-current components and may introduce ringing distortion.

Two types of light source were used, a thousand watt projection lamp and an AH6 high pressure mercury arc.

The addition of a metal reflector round the arc source directed a very broad sweep of light in the desired direction.

In 1876, Russian engineer Pavel Yablochkov invented a lighting system based on a set of induction coils where the primary windings were connected to a source of alternating current and the secondary windings could be connected to several " electric candles " ( arc lamps ) of his own design.

A searchlight ( or spotlight ) is an apparatus that combines an extremely luminous source ( traditionally a carbon arc lamp ) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction, usually constructed so that it can be swiveled about.

The radiation source is often a Tungsten filament ( 300-2500 nm ), a deuterium arc lamp, which is continuous over the ultraviolet region ( 190-400 nm ), Xenon arc lamp, which is continuous from 160-2, 000 nm ; or more recently, light emitting diodes ( LED ) for the visible wavelengths.

Unfortunately, projection required an extremely bright and therefore hot light source ( a carbon arc or a 500 watt bulb were typical ) and could visibly " fry " the plate if continued for more than two or three minutes, causing serious damage to the color.

The interior of the V is filled with transverse curved waves, each of which is an arc of a circle centered at a point lying on the path at a distance twice that of the arc to the wake source.

Maintaining a suitably steady arc distance is difficult if a constant voltage power source is used instead, since it can cause dramatic heat variations and make welding more difficult.

Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener ( surround channels ), providing sound from a 360 ° radius in the horizontal plane ( 2D ) as opposed to " screen channels " ( centre, left, and right ) originating only from the listener's forward arc.
