What is a pure resistance circuit? What is a pure inductance circuit?
什么是純電阻電路?什么是純電感電路?什么是純電阻電路? 交流電路的負載一般用電阻R、電感L及電容C三個基本元件表示。如果忽略電感L、電容C兩個因素，只考慮電阻R的作用，這樣的電路稱為純電阻電路，如圖1所示。圖1純電阻電路在純電阻電路中，當(dāng)電壓一定 ...JFEM500v電機引接線JFEM1140V電機引出線江蘇春晨
What is a pure resistance circuit? What is a pure inductance circuit? What is a pure resistance circuit? The load of an AC circuit is usually represented by three basic elements, such as resistance R, inductance L and capacitance C. If the two factors of inductance L and capacitance C are ignored, only the effect of resistance R is considered, such a circuit is called a pure resistance circuit, as shown in Figure 1. Figure 1 a pure resistance circuit in a pure resistance circuit, when the voltage is certain...

正弦交流電的有效值和平均值
The effective value and average value of sinusoidal alternating current
正弦交流電的有效值和平均值假設(shè)將交流電和直流電分別通過阻值相同的電阻，如果在相同的時間內(nèi)，這兩種電流產(chǎn)生相同的熱量，就把這時的直流電的數(shù)值稱為交流電的有效值。通過計算得出，正弦交流電的電流、電壓、電動勢的有效值均為其值的1/ ...
The effective and average values of the sinusoidal alternating current assume that the alternating current and the direct current will be resisted by the same resistance respectively. If the two currents generate the same heat in the same time, the value of the direct current will be called the effective value of the alternating current. Through calculation, the effective value of the current, voltage and electromotive force of the sinusoidal alternating current is 1/ of its maximum value.
