  1. 🙏 Namste sir, I can’t under stand how to calculate the resistance R1,R2,R3 using (l1-l2).
    and the temperature co efficient of platinum resistance thermometer is 0.00385/°C

      1. yes, but i can’t understand the formula of the platinum resistance thermometer Rt=r+ρ(L1-L2)

  2. Platinum resistance thermometer
    Iska video sir Griffith and Callender 3 in 1 instrument se kese kre reading kese nikale iska video bna do sir
