Question

how will you find coefficient of thermal conductivity of bad conductor​

Answer 1

Answer:

To determine thermal conductivity of a bad conductor (glass) in form of a disc using Lee's method. where H is the steady state rate of heat transfer, k is the thermal conductivity of the sample, A is the cross sectional area and (T 2 – T1) is the temperature difference across the sample thickness 'x' (see Fig.
