Emission spectrum of hidrogen is different from emission spectrum of sodium.Why?Ans) Because, in sodium atom there are already many other electrons present in the atom aother than the emisssion electron. There would be other forces too which will come into play. This is not the same as hydrogen atom, which has only one electron.
Explain Resistance Resistance: Interaction among flowing charges and atoms in electric circuit which resists (slows) current flow SI units: volt per ampere ≡ ohm (Ω)
