RESISTANCE TEMPERATURE CHARACTERISTIC(Rt)

.Rt is defined by IEC standard, pub.751:alpha=0.00385ohm/ohm/°C.

...For range -40°C. to 0°C. RT=Ro[1+At+Bt²+C(t-100°C.)t³]

...For range 0°C. to +150°C: RT=Ro(1+At+Bt²)

Constants in these equations are:
A=3.79782x10-³
B=6.502x10-7
C=4.3735x10-¹²

Rt=Ro[1+At+Bt²]
Rt=100[1+(3.79782x10-³x100)+(6.502x10-7x100²)]
Rt=100[1+.379782+.006502]
Rt=100x1.386284
Rt=138.628 ohm sat 100°C.
Rt=Ro[1+At+Bt²+C(t-100)t³]
Rt=100[1+(-.1519128)+(.00104032)+(.00003918656)]
