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.

Electric current is measured in amps.

You should notice here, when it gets up to 375, it says, Danger. Severe Shock.

Tension.

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

There is a great sense of tension in the air.

You could feel the tension in the air.

In the words of Fr.

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.

Tensions mounted.

Building tensions

Tensions were increasing.

Danger High Voltage.

Danger! High voltage.

Danger! High voltage.

What is the voltage?

Trade tensions continue to mount.

There was tension in the lines of his mouth.

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

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.

Brotherly tempers started to get strained.

Tom tried to ease the tension.

The Jews protested and tensions increased.

Here in Tbilisi, tension is understandably high.

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

But it is in the city of Taza where the social tension reached its peak.

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

It's not the volts that kill you, it's the amps.

Tensions have been escalating in this northern Hungarian village since March.

Strains and stresses paled when compared to the Soviet threat.

We want to neutralize the tensions. We want closeness.

Narrator Suspense, fun and intrigue.

Soon tensions were high on both sides of the divide.

It's been exhausting to follow the lead up to the referendum.

I felt the tension grow between us.

Using a larger value of resistance produces a larger voltage noise, whereas with a smaller value of resistance there will be more current noise, at a given temperature.

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

In Kosovo, Ban was able to lower the temperature on the boiling issue of the province s independence.

As a result, the uncertainty surrounding Obasanjo s plans is increasing sectional tensions.

But that can scarcely explain European nervousness and the protectionist reaction.
