I literally don't know what I'd do without these videos. I finally understand the forward/reverse bias stuff! Think I'll be watching these constantly for the next few weeks! Thank you so much for helping us out!
Thank you for the video!! Im a high school student in Korea and I had some difficulty on the diodes. Your video helped me understand it😊 Thank you so much👍
Thanks 👍👌👌👍 tomorrow is my exam so I think definitely it will help me once again thanks a lot so and I'm an Indian but your pronunciation and conversation is so easy understand.
Thanks - it's a tricky subject which isn't covered well in some of the summary books. Took me ages to study it and work out what I wanted to cover - all the best!
Most are already covered, at least with past paper solutions videos. I'll be trying to get out some more on the topics not done such as redshift and the doppler effect. All the best with your exam!
Question: I have not started my physics revision yet! Do you think i still have time? i have a month so i think i can cover all the topics in that time. Is it enough time to alteast get an A? Im just kind of nervous aha
The exam is on Tuesday 8th of May, so you've got over a month. Good that you're aiming high - make up a revision timetable and get started so that you can get the best result for you. The SQA apps are good for helping you with this and they have lots of helpful advice too. Go for it!
Only in that part of the depletion layer. The electrons will diffuse from the n-type to the depletion layer in the p-type. Before this, the p-type was electrically neutral - it may have one less outer electron than silicon but it'll also have the same number of protons. Since the electron moves into this region (which was previously neutral), it's now going to be negative.
