To Calibrate LPF wattmeter by Phantom Loading.\n
The phantom loading is that no external load is connected in actual sense and the current
it refers to the electric power consumed by electrical or electronic appliances when they are in stand by mode. eg:-tv, computer,laptop.
A: A voltage divider does not guaranty that the voltage will be set because the load on the divider will effect the value as part of the divider equation.
Phantom loading consits of supplying the pressure circuit from a
seperate low voltage supply. It s
