求翻译：功率因数的大小与电路的负荷性质有关， 如白炽灯泡、电阻炉等电阻负荷的功率因数为1，一般具有电感性负载的电路功率因数都小于1。功率因数是电力系统的一个重要的技术数据。功率因数是衡量电气设备效率高低的一个系数。功率因数低，说明电路用于交变磁场转换的无功功率大。是什么意思？

Power factor of the size and nature of the load circuit, such as incandescent bulbs, such as resistance furnace resistance load power factor is 1, the general circuit with inductive load power factor of less than 1. Power system power factor is an important technical data. Power factor is a measure

Power factor the size and nature of the load circuit, such as incandescent lamps, electric resistance furnace resistive load, such as the power factor is 1, which are typically electric inductive load the circuit power factor is less than 1. Electrical power factor is one of the important technical

Power factor big and small and circuit load nature related, like resistance load and so on incandescent lamp bulb, resistance furnace power factors are 1, generally has the inductive load electric circuit power factor all to be smaller than 1.The power factor is an electrical power system important

Power factor of the size and the load on the circuit nature, such as incandescent bulbs and electric resistance furnace resistance load factor is 1, generally with electrical circuit power factor inductive load is less than 1. Power factor is an important technology in power system data. A coefficie
