In choosing materials for transformer cores,what criteria is taken for the material in the case of its material resistivity and area of hysteresis curve to decrease eddy current losses?
Asked by saketh.pokala | 01 Feb, 2018, 03:34: AM
answered-by-expert Expert Answer
Area of hystersis curve should be narrow so that energy dissipation in the material is less and causes less heating.
Resistivity should be high to lower the eddy current losses

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
