I was never a "studious" kinda student and even if I try to study and try to solve the numericals I couldn't. Sometimes I used to leave them by looking at the length of question. But today I can actually solve many questions. I ain't saying I can solve every question out there but yeah, I've improved a lot in physics. Heartily thankful of you sir 🥺🖤

    Just a small correction at 1:06:30- Normal broadband connections are made up of twisted pair cables , optical fibres are usually used to transfer data from continents to continents or within country. ISP's provide a lower quality optical fibre at cheaper rates which are now in frequent use but they are optional....the wires in lan port are of copper and not of fibre
