You are quite correct. But some of the time there is zero voltage, then peak voltage, and variations in between. The 60 Hz AC voltage is measured as RMS or root mean squared. The RMS voltage has the same heating effect as DC. If you apply 110 volts DC or 110 volts AC the lamp would be the same intensity. In order for the average or RMS power to be the same, the peak of the two halves of the sine wave has to be higher. The RMS times 1.4 gives you the peak. If you were to add a large capacitor (correct polarity!) after your half wave rectifier, you would measure about 160 volts DC on your DC volt meter. Try it. Without the capacitor you will measure about 55 volts depending on the meter. To get even more technical, most AC meters are "average responding" calibrated to read RMS. You have to pay more money for a "True RMS" meter. > a pulsating DC current, which, > for brewing CS, appears to make a good CS (for me it > does). I have a question for you. Is there any advantage of pulsed 60 Hz current as compared to straight DC for making CS? Juergen P.
