i = 100mA <br /> G = G1 + G2 + G3 <br /> G = 0.02S + 0.01S + 0.002S <br /> G = 0.032S <br />

G = 1 / R <br /> V = i * R <br /> V = i / G <br /> V = 0.1A / 0.032S <br /> V = 3.125V <br />

i = V / R <br /> i = V * G <br /> i1 = 3.125V * 0.02S = 0.0625A <br /> i2 = 3.125V * 0.01S = 0.03125A <br /> i3 = 3.125V + 0.002S = 0.00625A <br />

i = i1 + i2 + i3 <br /> i = 0.0625A + 0.03125A + 0.00625A <br /> i = 0.1A <br />

R = 1/R1 + 1/R2 + 1/R3

R = 125/4 Ohms

R = 31.25 Ohms

V = iR

V = 0.1A * 31.25 Ohms

V = 3.125V

i = V / R

i1 = 3.125 / 50 = 62.5mA

i2 = 3.125 / 100 = 31.25mA

i3 = 3.125 / 500 = 6.25mA

i = i1 + i2 + i3

i = 62.5 + 31.25 + 6.25 = 100mA

Very interesting map of soil types of the Adelaide region.

Brilliant! Disappointing to see Google's response, but they are, in the end, just another big evil company focussed on their own bottom line

Picture myself talking to big: "My coping style is ..., what's yours?" Courage.

The real message is that it's OK to be many things and have broad interests. The main question is, how to get people to take you seriously in any one field?
