Sentence examples for voltage from inspiring English sources

The zoo is also spending £5,000 installing a "voltage optimisation unit" to reduce the mains voltage of 240v down to 220v to help prevent any needless waste of electricity.

He died in hospital an hour-and-a-half after being shot with the Taser, an electroshock weapon that fires high voltage electricity which should temporarily disable, but not kill, its victim.

By applying a small voltage at right-angles to the layers they found they could pull the ions towards the aluminium oxide, clamping them in place and thus controlling when the current flowed the essence of a transistor.

But because of the relatively low voltage and the drop in the line, a DC generator could reliably serve customers only within a radius of a mile or so.

Thermal losses caused by electrical resistance in a line are proportional to the square of the current, so the lower the current (and the higher the voltage) the more efficient the system.

For instance, the power delivered by an AC line is defined by the root mean square (ie, 71%) of its peak voltage.

In all cases, high-voltage transmission is the key in getting this renewable energy to markets.Last in line are the fossil fuels and nuclear.

A high-voltage DC system can therefore carry 40% more power for a given current.

Finally, high-voltage DC provides a handy means for synchronising AC systems that operate on different frequencies.

We must flip the old energy model upside down.In the last century, utilities met new demand by building large centralised coal, nuclear and hydro generation plants and linking high-voltage transmission to our cities and industry.
