Q2 You are an electrical inspector to measure the horizontal illuminance over the work plane of a rectangular room. Given : The size of the room is 10 m length x 7 m width. The illuminance grid p = 0.2 x 5logd, where p is the maximum grid cell size (m), d is the longer dimension of the area (m). (a) Calculate the value of grid point spacing. (b) Determine the number of grid points (c) Draw a detail grid points diagram and mark a "x" at each of the measuring points on your drawing.
