.(1)Electron's potential energy decreases when it moves from lower to higher potential,right?And i also want to verify few more things on which i am doubtful .(2)Why when electron passes through resistance it's potential energy decreases?I think because it require energy to pass or cross resistance as it is hindrance for flow of electron so when electron crosses this it does work i.e uses energy that's why it's energy which was totally in the form of potential energy get reduced,so that's why when electron passes through resistance it's potential energy decreases.right? (3)But why electron's energy is totally in the form of potential energy,as it was moving through circuit it should have kinetic energy also.Is kinetic energy negligible as mass of electron is very small .I don't think so it is right.And if it has kinetic energy, why after crossing resistance only it's potential energy decreases,why not kinetic energy decreases i.e why not electrons get slow down after crossing resistance? Although i have put 3 questions together we can discuss one by one.Just guide me where i am wrong. Regards.
