例句與造句

1. When the battery is disconnected while the engine is running, a load dump transient can produce very high voltages as the built in voltage regulator has been controlling the alternator field current to charge the vehicle battery and although it will attempt to reduce the field current to keep the output voltage constant, the field winding is highly inductive and setting the current to its new value takes several hundred milliseconds, during which the alternator output voltage will exceed its intended value.
2. It's difficult to find built in voltage in a sentence. 用built in voltage造句挺難的
