Electricity from the power company is delivered as alternating current.

We have an inverter in there, so you get 117 volts A.C.

We have A.C. and D.C., get 12 volts D.C., so that could be used for certain applications.

In 1919, alternating current welding was invented by C. J. Holslag but did not become popular for another decade.

Local systems in one building could be connected to local low voltage DC or 230V AC grids to improve the security of supply.

When single phase or three phase 230V AC power is needed (say, to power larger machines), an inverter must be used.

You need an entry ticket.

How much does an entrance ticket cost?

I went up to the front door.

Where can I buy an entrance ticket?

Electric current is measured in amps.

Someone is at the front door.

Where can I buy an entrance ticket?

Combining projection mapping and a pop up book, Marco Tempest tells the visually arresting story of Nikola Tesla called the greatest geek who ever lived from his triumphant invention of alternating current to his penniless last days.

Noise is produced by the sudden flow of current into a solenoid.

The term on the right is the divergence of the current density .

An ammeter is a measuring instrument used to measure the electric current in a circuit.

The flight of stairs to her room went up from a landing of the well heated front staircase.

In it, he showed the equivalence of electrical currents to magnets and proposed that magnetism is due to perpetually flowing loops of current instead of the dipoles of magnetic charge in Poisson's model.

Even more crucial has been the enormous drop in the cost of transmitting information, which reduces barriers to entry.

When Tom reached the front door, he noticed it was slightly open.

Autumn leaves crunched under Tom's feet as he walked up the path to Mary's front door.

If too much current is flowing, the intelligent receptacle turns itself off, and prevents another fire from starting.

Their purpose is to measure the illumination level in the interior and to switch off or reduce the output level of luminaires.

STEPS WERE HEARD AT THE ENTRANCE, and the Princess Betsy, knowing that it was Anna, glanced at Vronsky.

Anna looked out and saw Karenin's messenger in the porch ringing the bell.

The test button (8) allows the correct operation of the device to be verified by passing a small current through the orange test wire (9).

Seiring dengan manfaat lain yang timbul dari upaya upaya memperbaiki pengelolaan listrik dari sumber tenaga yang berfluktuasi, biaya tenaga surya akan terus menurun.

This is Motor Ritz Towers in Manhattan in the 30s, where you drove up to your front door, if you had the guts.

Technological breakthroughs have made it feasible to transport electricity via high voltage direct current (HVDC) over long distances without incurring great losses (only about 3 per 1,000 kilometers).

So these three psychiatrists, after about two or three weeks of observation, laid him down on a table, connected his temples to a very small source of current.

Direct current lines need to be constructed to carry solar and wind energy from sunny, windy areas to where most people live.

The most common DC voltages are 600 and 750 V for tram and rapid transit systems, and 1,500 and 3,000 V for mainlines.

I was downstairs by the front door, and I was waiting for a taxi, and my son came down the stairs and he'd made a card for me. And he was carrying it.

That is, that the resistance, the ratio of the applied electromotive force (or voltage) to the current, does not vary with the current strength .

NEW YORK Whenever I hear people on America s Republican right call themselves conservative, I experience the mental equivalent of a slight electric shock.

Built around the old city and spreading out into its downtown and Soviet era sections, Baku boasts a magnificent combination of Oriental and European architecture, the result of historically being passed among the Persians and Russians.

At half past twelve in the night, the fans left the building of the railway station, however one of them, a 22 year old young man, suddenly returned and used his leg to break a window of the entrance door in the station's waiting lounge.

One sultry, sticky morning, I woke up to find a long column, about 20 feet long, of tiny black ants trooping through a crack under the front door, up through the entry hall, and into the kitchen.

Any electrical device an appliance, an extension cord, whatever must be able to tell the power outlet, Hey, power outlet, I'm drawing too much current. Shut me off now, before I start a fire.

CALGARY When Harvey Cushing and William Bovie introduced electrocautery (which uses a high frequency current to seal blood vessels or make incisions) in 1926, their innovation transformed neurosurgery.

Two officers appeared at the entrance door one with a weak thin face, a young officer who had just joined the regiment from the Cadet Corps the other a plump old officer with a bracelet on his arm and small eyes sunk in a bloated face.

Without money to pay polleros (human smugglers) and to avoid checkpoints, thousands of migrants ride on the tops and sides of railcars where they are exposed to rain, extreme temperatures, dehydration, and electrocution.
