answered-by-expert Expert Answer

The difference between ac current and dc current is its frequency. The frequency of a dc current is zero. The frequency of ac current is something higher. The danger from electric current vary with frequency.

Also the voltage is not important but the electric current that flows ultimately.

At DC, your skin is a high resistance insulator. At very high frequency, your skin is a low-impedance capacitor.

Hence, AC with high frequency is dangerous than DC.

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?
