The resistance of material will change per degree of temperature change,RTD is a positive temperature Co-efficient i.e resistance value will increase whenever temperature increases.
At 0 degree celsius Pt100 have 100 ohm,resistance will increase by increasing temperature .
To calculate R-R0/R=alpha*(T-T0)

Answer / nitish katoch

Resistance will increase at 1000 ohm per degree celsius for
pt1000
