Voltage

at 4:42, qE(d1-d2) as E*d1=V1 , E*d2=V2 ,so eventually q(V1-V2). I was stuck here and found out the connection, like qE is force similar to mg is a force. Thanks sir.

Nice

At 3:30 the object "gains energy". Actually no energy is gained. It is converted from potential energy to kinetic energy. Maybe you meant to say it "gains kinetic energy"?

[@aruntejareddy7198]

@David same doubt it loses potential energy

😥 Nptel me bhi mistake hai

Voltage in circuits is entirely due to gradients in surface charge. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism. It will be instructive to understand Current, the conduction process and Voltage at the fundamental level as in the following two videos: i. kzbin.info/www/bejne/ioXXpWVul5aXj9E and ii. kzbin.info/www/bejne/bnO0fpKurJeFnNE The last frame References in video #1 lists textbooks 3 and 4 which discuss details about resistance, how current branches in a parallel circuit and ohm's law. See these lectures by North Carolina State Univ faculty which use a unified approach to electrostatics and circuits. 15. Simple D.C. circuit. Pattern of electric field. Watch from 16.0 minute. 16.
