what is a voltage 要具体的解释,举一个例子来反映这个单词的意思 要英文的 Dropout voltage is the input voltage minus …………Dropout voltage is the input voltage minus output voltage that produces a 1% decrease in output voltage请问这句话是啥意思?minus在这是什么意思 A major factor contributing to voltage instability is the voltage drop that occurs when active and A major factor contributing to voltage instability is the voltage drop that occurs when active and reactive power flow through inductive reactances of voltage 英语翻译In the case the inverter operation as a voltage source,the output voltage is of rectangular form and output current waveform can be forced sine independently on the load character by means of pulse-width voltage modulation. 英语问题懂的进来拿分 12.A flashlight bulb uses 8.4 W of power when the the current in the bulb12.A flashlight bulb uses 8.4 W of power when the the current in the bulb is 0.6 A.What is the voltage difference?What is the resistance of the fl 这个句子为什么要用不定式the test potential is to be increased to the test voltage不能说成The test potential increased to test voltage吗? 我的G18刷PG58IMG时显示battery voltage is too low!please charge a batttery,请问为什么? 英语翻译Power is the amount of current times the voltage level at a given point measured in wattage or watts. 英语翻译Third harmonic voltage phasor is evaluated on the basis of kth samples block,which contains values of entire voltage measured in generator terminals or neutral.The result of kth third harmonic evaluation is compared with value evaluated a 英语翻译TransformerTypes and construction of TransformerA Transformer is a device that changes ac energy at one voltage level into ac electric energy at another voltage level through the action of a magnetic field .It consists of two or more coil 英语翻译high voltage is necessary for long transmission line while low voltage for safe use. 英语翻译Accordingly,the selected interim pulse can be one at which the voltage is above a predetermined level for efficient erase procedures,but less than the maximum erase voltage to be applied. 英语翻译It works with both regulated and unregulated externaldc supplies.If a non-regulated supply is chosen,the supply unit should have enough capacitance to hold upthe supply voltage to the minimum required input voltage at maximum load 英语翻译In conformity with the following examination conditions,voltage is directly impressed among the terminals until after [of a vent operation] 1 minuteOn the following examination conditions,even if it results after [of voltage impression]5 英文电机题,求指导!A 50hp,250v dc shunt motor has an armature resistance of 0.06ohm and a field winding resistance of 50ohm.The no-load speed at rated voltage is 1200rpm.Neglecting armature reaction,what will be the speed of the motor when its 英语翻译Where a built-in arrester is provided (suffix code:/A),the voltage for the insulation resistance test must be 100V DC or lower,and the voltage for the withstand voltage test must be 100V AC or lower.Failure to heed these guidelines may ca What is a family?
