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.

Where's the light switch?

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.

She pressed the switch.

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.

Mountains and oceans are hard to move, but portions of cyberspace can be turned on and off by throwing a switch.

That was to come much later the off switch on appliances because it didn't make any sense.

Tom keeps a food diary.

Jones, Loyd A., and H. R. Condit.

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.
