| 31. | :There is also the issue of alternating current and direct current.
|
| 32. | The generator in a wind turbine produces alternating current ( AC ) electricity.
|
| 33. | :: Would the A C mean something other than alternating current?
|
| 34. | Ultimately this type of alternating current technology never developed and was not used.
|
| 35. | The railway essentially became a test site for alternating current electrification.
|
| 36. | With alternating current voltage can be changed up or down using a transformer.
|
| 37. | But they lost significant amounts of energy when conveying alternating current, or AC.
|
| 38. | The second topic is the elementary theory of alternating currents.
|
| 39. | Then, the probe opens like an umbrella with alternating current sent up the spokes.
|
| 40. | We spoke of alternating current and direct current and who was better at that.
