Calculating and use c Use the arduino to model a voltage for

Use the arduino to model a voltage for the network put together a but provides 12VDC to the below. When the voltage drops to control board should light up an LED untill the voltage gets to a representative The second board will represent the Var compensation. When the first board lights the last representative of the 12.6V, a relay should switch a capacitor in parallel into the increases the power factor to 95% based on calculations. l need to see a demonstration and calculations. If you have any questions.

Solution

V = I*Z

120 = I(200+ 240*3.14j)

I = 120/(200+ 240*3.14j)

Vdc = .95* Vac

so that all 4 are connected in parallel
