Load characteristic curve

Witryna12 paź 2024 · The curves OC and OD represent internal and external characteristics respectively. Since load current and field current is the same, an increase in load current causes the terminal voltage to increase. Beyond a certain limit, the terminal voltage starts decreasing with an increase in load. It is shown as a dotted line in the above … WitrynaFIGURE 6: Volt-amp characteristic of a self-excited DC generator. As the load increases (meaning the load resistance decreases) the armature current increases. Based on the factors listed, the generated voltage would decline as the load increased. ... The decrease in load current causes the volt-amp characteristic curve to turn …
