V_{tpd}\) can also be calculated as \(I R\) where \(R\) is the load resistance. Voltage is a measure of energy, and energy is always conserved. So the EMF \(E\) of a cell is equal to the sum of ...

IN a recent paper, 1 Gerlach and Schneiderhan have described some experiments on the electrical resistance of nickel as a function of the temperature and as a function of a longitudinal external ...

Discover how electric resistance water heaters and heat pump technology are transforming the energy efficiency of water heating. Learn about the potential of thermal batteries and how they can ...

I AM indebted to Mr. Herbert Tomlinson for drawing my attention to his most interesting comparisons between the behaviour of carbon and of metals in respect of change of electric resistance under ...

Superconductivity is a fascinating phenomenon in which certain materials exhibit zero electrical resistance and expel magnetic fields below a characteristic temperature, known as the critical ...
