Once the key S is closed as shown in fig(a), 5Ω resistance is getting shorted.
Hence as shown in figure 10Ω and 20Ω are connected in parallel to 10 V battery.
Potential difference across each resistance is now 10V. The path a-to-b is connected to 10Ω resistor.
Hence the current in the path a-to-b is 1A as shown in fig(b)

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?
