A platinum resistance thermometer reads ...

A platinum resistance thermometer reads `0^0` when its resistance ia `80 Omega and 100^0` when its resistance is `90 Omega`. Find the platinum scale at which the resistance ia `86 Omega`.

Text Solution

Verified by Experts

`R_1 =86 Omega R_0= 80 Omega R_100=90 Omega`
`t= R_1-R_0/R_100-R_0 xx 100`
`86-80/90-80 xx 100`
`6/10 xx 100= 60^0C`
