Both the maximum … WebEach of these waves have a voltage amplitude—the "forward" voltage V f and the "reflected" voltage V r. The conceptual problem comes from the dials of the directional wattmeter, which are not calibrated in volts but rather in watts.
WebThis video covers why there are restrictions with motor lead length, and the effects of reflected wave on those motor lead lengths. When motor cables go lon... WebAs shown in Fig. 17.13, the incident voltage is reflected with the same amplitude but 180° out of phase. The incident and reflected waves will sum together to produce a standing wave, otherwise known as a stationary wave, as will be demonstrated below. Sign in to download full-size image Fig. 17.19.
