DC Watt Meter, Amp Meter & Amp Hour Meter Simulator - The First Online!
To get a better feel for a DC Watt meter's functions, give this simulation a try. It's easy to use.
You can set electrical values for experimental sources and loads and see how changing parameters changes the readings on the "Watt's Up" meter display. You can vary things like source voltage, "throttle" settings, and the resistances of your battery, motor & controls, wiring, etc. and see their effect on your electrical system.
Use your mouse to adjust the sliders and arrows to change values. The meter values change to show you what's going on.
