| Most of these have existed for some time, and current is supplied through a third rail bringing direct current at about 800 Volts. |
| This then transforms the energy into the direct current that the battery uses to recharge. |
| In contrast to direct current, polyphase AC systems proved capable of transmitting power hundreds of miles. |
| There is a alternating current, instead of a direct current within the bobbin because of the motion of the string. |
| The wind plant captures and transforms wind energy into direct current electricity. |
| A circuit arrangement for supplying a discharge lamp with a direct current includes input terminals for connection to a supply voltage source. |
