[@aamnakhan7856]

45 minute pe kuch opposite nhi bol gye sir? if we move a charge, opposite to the direction of electric intensity it will gain potential energy and vice versa...... am I wrong

[@shamamanizamani]

electron ko move Hum nh karwa rahey oppositly, ye electron khudi move kar raha hai opposite to the direction of electric feild lines, kyu ke its a property of a negative charge to move toward positive and thats what electron is doing here, its like hum ne electron ko khula chor diya hai ab wo khudi positive ki tarf jaa raaha hai, , mtlab ab electron kinetic energy gain kar raha hai due to attraction of positive terminal or isi wajha se wo Potential energy ko loss karega, or hence hum koi work bhi nh karwa rahe, tabhi work will be positive here kyu ke electon khudi work kar raha hai or khudi positive ki tarf jaa raha hai, and uskey upar koi external force laga ke usko work nh karwaya jaa raha.

[@shamamanizamani]

Baaqi rahi baat peechey jo sir ne points batayi, jis men charge ko against the electric feild lines move karwa rahe the and Potential energy loss ho rahi thi, wo is liye ke wahan hum positive charge ko le rahe the, or positive point charge jab positive terminal ki tarf jayegi to zahiri baat jai hai ik doodrey repel karen ge, or usi wajha se humen external work karna parega, or us wajha se wo charge potential energy bhi gain karega, potential is liye gain karega or kinetic is liye loss karega because potential energy ki definitation says energy gain due to position or hum yahan pe yehi to kar rahe hen, external work kar ke, against the feild lines move karwa ke,kisi position pe positive point charge ko le jana chah rahe hen

46:46 can someone explain, when electron moves against the Electric field, work done is +ve or -ve...??

[@murkloungani780]

It's +ve work done. Because electric field lines are always from +ve to -ve (→) And if electron is moving against it (←) it means it is moving towards +ve charge. So electron has -ve charge and it is moving towards +ve charge so they will attract each other and electron will move by itself. So this will be called as +ve work..
