I am that impressed with these tutorials I will be watching them all. (1-16). Returning to studying electronics after about 25 years. These are helping me keep my mind occupied during this lock down period. Stay safe and healthy. Thank you.
With the switch closed, you have a parallel circuit so current flows through both wires inversely to the resistance. The resistance of the wire is considered negligible compared to the bulb so nearly all the current will go trough the wire. A very small, negligible current will flow through the bulb, but will not be nearly enough to light the bulb.
Soo this means that 2 bulbs means 13W in total and 3 bulbs means 9W in total? I'm trying to understand why both circuits didn't have the same power. This means that resistance must be low to have higher current and voltage and make bulbs efficient but what can make them burn for exemple? If I have a 100W bulb it should work with both 100V and 1A and also with 100A and 1V,if it can be possible to have those 2 extremly different values of voltage and current. So what can cause a bulb to burn, voltage or current?
I have a whole play list about resistors in series and parallel I could also email you some exercises if you give me you email address. What exactly are you looking for? Does that help?

Here are the links to a couple of videos I made about electric power. Is this what you are looking for? th-cam.com/video/41-37Kv_ljw/w-d-xo.html th-cam.com/video/2cuNnN_Cop0/w-d-xo.html
Is there a video about what happens if the bulbs were replaced with low power bulbs such as LEDs? LEDs would have lower resistance, which from this would result in higher current, but actually results in lower current an power in the circuit. Can anybody explain or point me to a video that explains why? Thank you.
Point of information; We in the lighting industry NEVER say "bulb". In honor of those who came before us [ and suffered centuries of living with oil lamps] , we refer to a lighting device, incandescent, flourescent, arc or LED, ..... as a "LAMP".
Sorry, when I was growing up we always called them light bulbs. Now I am teaching in Berlin Germany when a light bulb is known as a Glühbirne. The literal translation is "glowing pear". It glows and it looks like a pear.

This provides a little more clarity. I was stressing really bad, but now I feel like I have a better grasp, thank you.
Great to hear! Thanks for watching!

Thank you.
Glad you like them! Thank you so much for the great comment.
Clear and concise.
Love to hear that, thanks!
Excellent, so well explained
Thanks, glad you think so!
This was a great video!
Thanks for watching and commenting!
Why is it when the switch is close, current do not flow through bulb 1? Doesn’t current take all paths available?

noob question: when the switch is closed, nothing goes into bulb 1? it does not emit any light at all?
It still will be hot aswell
Thank you so much ! Can't explain your help
Can give us exercises about resistors

It's actually good but can you make a video about electrical and power energy

Sorry, I have not yet made such a video.
Thanxx sir😁😍

@@carpediemyes OK
what the hell are you saying? in honor of those who lived without bulbs? then your rule only is for American citizens not for German's
