Resistance and reactance are the properties of an electrical circuit that opposes the current. The main difference between reactance and resistance is that resistance measures the opposition to a flow of current, whereas reactance measures the opposition to a change in current.

1. Electrons revolved around the nucleus in certain permitted non-radiating orbits. Centripetal force to revolving electron is provided by electrostatic force of electron and nucleus. "mv^2/r=Kze^2/r^2" 2. Angular momentum of the electron in stationary orbit is an integral multiple of h/2(pi). " mvr=nh/2(pi)" 3. Energy is radiated when electron move from some higher energy level to lower rnergy and energy is absorbed when electron move from lower to higher enrgy level. "hv(neu)= E2-E1"

Sangeeta Nara 6 years, 10 months ago

1.Every atom has a central core ,containing all the +ve charge i.e nucleus.... 2.All the e- revolve around the nucleus in fixed energy path ..... 3.Angular momentum of every e- is intiger multiple of h/2π ..i.e mvr=nh/2π
