We know that electron are responsible for carrying negative charge and it has mass. I read somewhere Positive charge is carried by holes so how a massless thing can carry a charge????

It begins with taking a renowned condition and not understanding when it is appropriate. E=mc2 is the vitality of a molecule of mass tangle rest; an opening is never very still and in this way this condition is not material to it. The vitality of any molecule is E=√[m2c4+p2c2] where p is the direct force. Take note of that if p=0, the molecule is very still and in fact E=mc2. On the off chance that m=0 then E=pc. Mass less particles have force. The main massless molecule we know is the gap which has a vitality E=hf where h is Planck's steady and f is the recurrence. So the force of a photon is hf/c. with respect to rest of your question, when an electron drops to a lower circle the mass of the iota diminishes by precisely the perfect add up to supply the vitality to the photon. At the point when a photon is consumed by an iota, then again, the particle ends up noticeably energized and hence more gigantic.
