英语翻译An antenna is a device that converts RF power applied to its feed point into electromagnetic radiation and intercepts energy from a passing electromagnetic radiation,which then appears as RF voltage across the antenna’s feed point. 答案 天线是一种把运用于其馈电点的射频电源转化为电磁辐射的...
CONVERTech High Voltage Power Supply Model-SHV300维修 对于机器工作不稳定或工作时好时坏,可检查箱内主电路的螺钉、接线端子等等是否松动(在运输中有可能会出现)、接线端氧化等,老电源或使用环境差的电源应注意内部是否积了很多灰尘(可用风枪吹掉);如箱内积有很多油污且使用期很长,不可修复应报废处理 ...
● Conversion: Voltage V to Level, dB, dBu, dBV, and power level dBm with impedance value ● Usually we measure AC voltage V as voltsRMS. The RMS value of a set of values is the square root of the arithmetic mean (average) of the squares of the original values....

With this technology, microwaves with a power level of 100 nanowatts (nW) can be converted to electricity. Going forward, as the research group optimize the design of the diode and the radio wave-collecting antenna while adding power control for constant voltage, there are high expectations for...
The power of this discharge in the electric lighters is so small, that its energy is only enough for heating the gas to its temperature of combustion. Lightning and the Ionosphere The power of single lightning at an average voltage of 20 million volts and a current of 20 thousand amperes ...
power conversion efficiency of the cell. This approach is useful because it allows comparing cells made by various manufacturers. While the voltage from the photovoltaic module is determined by the number of individual solar cells, the current from the module depends mostly on the surface area of ...
