Unit: m/s2*acceleration due to gravity g Acceleration of a body falli。

3、PEC 电气工程专业英语证书考试-Glossary of Electrical Engineering Terms3o AmpereThe measurement of intensity of rate of flow of electrons in an electriccircuit. An ampere is the amount of current that will flow througha resistance of one ohm under a pressure of one volto Ampere RatingThe current-carrying capacity of a fuse. When a fuse is subjected toa current above its ampere rating, it will open the circuit after a predeterminedperiod of timeo Ampere Squared Seconds, l2tThe measure of heat energ。

4、PEC 电气工程专业英语证书考试-Glossary of Electrical Engineering Terms5AC Signal: The time variant portion of a voltage or current.Alternate Sweep: A vertical mode of operation for a dual-trace oscilloscope. The signal from the second channel is displayed after the signal from the first channel. Each trace has a complete trace, and the display continues to alternate. This mode is used for SEC/DIV settings of less than 1 ms/div (faster than 1 kHz).Alternating Current (AC): An electric current whos。
