WebA dc short-shunt compound generator operating at a terminal voltage of 112 volts is delivering 19 amperes to its load. If its armature resistance, series-field resistance, and shunt-field resistance are 0.161 ohm, 0.210 and 90 ohm respectively, determine the generated voltage in volts of this machine. Assume 2 volts brush drop. WebJun 5, 2013 · High load = the generator has to work hard to power it, that means that the power output is high. Conversely, low load means that the generator does not have to work as hard = lower power. If the voltage is constant then higher power means higher current and lower resistance. fnf triple trouble sonic online
