Calcular el valor Id

Id = 0.024 · d + 0.11 · (d – 177.3) · H(d – 177.3)

Id = 0.024 · 2.23 + 0.11 · (2.23 – 177.3) · H(2.23 – 177.3)

Id = 0.05352 + 0.11 · (-175.07) · 0(2.23 – 177.3)

Id = 0.05352 + 0.11 · (-175.07) · 0

Id = 0.05352 + 0.11 · 0

Id = 0.05352 + 0

Id = 0.05352

Calcular el valor R

R = 94.2 - Id - Ie

R = 94.2 - 0.05352 - 0

R = 94.14648

Escala MOS

MOS = 1 + 0.035 * R + 7 * R * (R–60) * (100–R) * 10^-6

MOS = 1 + 0.035 * 94.14648 + 7 * 94.14648 * (94.14648 – 60) * (100–94.14648) * 0.000001

MOS = 1 + 3.2951268 + 7 * 94.14648 * (34.14648) * (5.85352) * 0.000001

MOS = 1 + 3.2951268 + 7 * 94.14648 * (34.14648) * (5.85352) * 0.000001

MOS = 1 + 3.2951268 + 0.13172408016207
