/* Resistor in end line for vertical sgement */
==== Resistor in end line for vertical sgement ====
if the segment is alone, the end line resistor is of (example each element of the X letter) :
<math>
= '''40 mW'''
if the segments are linked by two, the end line resistor is of (example for the F, I, M, E letters) :
<math>
R_{1Seg} = \frac{Vcc - U_{seg}}{I_{LED_{Seg1}} + I_{LED_{Seg2}}} = \frac{12V - 10V}{20mA + 20mA}
</math>
= '''50 Ω'''
<math>
P_{R_{1Seg}} = R_{1Seg} \cdot (2*I_{Led})^2 = 100 \cdot (40mA)^2
</math>
= '''80 mW'''
