Draw the experimental set-up to verify `V//I` is constant for a conductor.

How do you prove experimentally the ratio V//I is a constant for a given conductor ?

What are the material required to show that the V//I is a constant for a conductor ?

(a) Define the term 'latent heat of vaporisation' of a liquid. What is the value of the latent heat of vaporisation of water ? (b) Draw a labelled diagram of the experimental set-up to study the latent heat of vaporisation of water.
