But, why do we use the rms value? We could use, for ... ,In that case 10V rms sine wave has a 14.14V peak and 28.28Vpp ... is being referred to, Vac and Vrms then being numerically the same, so 5Vac= 14.14Vpp. ,For read operation Vac and Vpp must be +5V i5%. Supply current is 90mA, standby 20mA typical. For programming mode, Vcc must be taken to 6V 10.25V and ... ,This is a peak-to-peak voltage calculator. It calculates the peak to peak voltage value from either the peak voltage, rms voltage, or the average voltage. ,Following is the formula for Vpp to Vrms conversion. Vrms = 0.3535 * Vpp. Where Vpp is the peak to peak volatge and Vrms is the root mean square voltage. , Vpp=VCD=50V, Vp= 1/2 Vpp= 50/2= 25V 而Vrms = Vp/1.414(開根號2) = 25/1.414= 17.68 V (Vac). 所以你要的公式, 簡單的回答=~ Vac= (VDC/2)/ ...
