Final Exams and Video Playlists: www.video-tutor.net/

Went through at least 20 vids on how to do this and your explanations covers it all perfectly and without dead ends, Thank you very much.

you are just here to make our lives easy. u are such a blessing to us🙌🙌👏👏👏

Thanks for this! I went through it twice with you. First I listened and followed the best I could. Then I took out pencil and paper and worked out every problem trying to stay just ahead of you by pausing your video of course. This was very helpful at driving it in. You made one small error on screen by writing 12v when calculating watts used by R3. I did stumble on this, but finally realized you were saying 24v but writing 12v. Not sure who else caught this, but it actually helped me learn it better, by working a bit harder to figure this out. 😉🤪

hey man you have helped me so much over the last year, thank you for breaking it down.

not everyone explained it well like you. thank you very much . I am glad i found this video .

thank you so much for not confusing me so much like my instructor!! bless your heart!

thank you so much for not confusing me so much like my instructor!! bless your heart!

All of your videos are stunningly effective and beautiful. 👍 FWIW at 9:39 forgive me if I am mistaken butI believe that the written 12V should have been 24V. Kindest regards.

thankyou for this gift professor you made my life much easier and this is beautiful. Your video is more useful than a textbook with 20+ pages on the topic.

This was so helpful. Thank you so much.

I'm sure you get this a lot, but thank you for clearing up the comprehension of circuits! ☺️

These videos really help me to answer my modules

Amazing! Thank you

Best channel on yt. Just saved me mid exam.

Thanks a lot. This video was really helpful 👌

Woahhh you know everything what a legend

Thank you so much... I genuinely had no understanding of the circuits before watching your videos. Should have watched them earlier

great video!!

That was insane brooo

thank you so much!!

Really thanks a lot 😍

U are just, just saved me bro thanks alot

There's an easier way than the reciproca of the sum of the reciprocals. It transforms algebraically to the product divided by the sum: e.g. R1*R2/(R1+R2).

That is correct, but only possible with two resistors. If there are three or more, we have to use the longer method.

I don't see how this is easier in any meaningful way. Plus, it only works with 2 resistors.

Excellent I'm struggling with this even in the learning resources and I've got the BIG closed book exam tomorrow and this is a weak area for me

ERROR ALERT: In the last example at 9:35 you said that you were going to use the forumula P=(V)(I) then you plugged in 12 for voltage and 3 for current but still came up with 72W. I thought I was losing my mind! Otherwise, great video. Thank you.

Could you use one equation for power to work out question B ?

Please help me. I am trying to figure out how to use Mean Well LPV 60 12 LED Driver with 230 volt AC. I guess I have to use resistors in order to that. If it's rated for 60 watts, what components I've to buy in order to plug the power supply to 230v electrical socket. This power supply has voltage - Input (Max) 264VAC and has IP67 rating

When finding the power pulled from each resistor you used a different formula eg R1, I²XR1 R2, V²XR2 and R3 VxR what if there 4 resistors how do I know which to use

At 5:06, there’s also a third way to calculate the total resistance.. R= P/I^2 So, 60 W/5 ^2 A equals 2.4 ohm

5:15 taking notes! thanks for this video!

still dont get where you got one over something -1 for total resistance, but the simple ohms law for resistance works fine :)

how did he find 5amps in the first example??

I love you ❤️ ❤️

whar if you dont have volt calc

for p3 is there not 24v across? I thought voltage was constant in a parallel circuit. p1 and p2 had 24 through them.

What if there are 9 resistors in parallel circuit ? How to solve it?

please take this symbolic portion of my professor's salary 🤲

P3=VI why the V is 12? Not 24? Why I is 3A?

Why not use P=VI when computing for power absorbed by each? R1's Amp/I is 3, then the voltage is 12V, so product is 36. Same goes for R2. No fancy equations.

How do you get the V when only total Current and r1,2,3 are given?

Why the current goes through 6ohm resistance..it will choose low resistance path of 4ohm no??

@HollowHimself

3 жыл бұрын

If you think of the current like cars/traffic and resistance how narrow the road is; even if you have a nice wide road (4ohm), it would still be smart to go down the thinner road (6ohm) as well, because you can fit more cars down BOTH roads than down just one road. Hence why the total resistance is 2.4ohm, BOTH roads combined let more cars through.

9:54 you made a mistake in P(eqn 3)=VI=*24* x3

I watched it.

but this rule works only if it consist only Parallel circuit, if we have mixed then don't use it.

Where did the 2 amps of current came from? @1:23 Nvm I got it…🥴

Sir why I do it in actual but the result of computation didn't get the same result in multimeter?

Find the equivalent resistance and apply Ohm's Law?

your method of solving for the power in the second resistance does not follow the rules of PEMDAS. correctly solved it is 12*12= 144/ 6 = 24Watts

Which way current is flowing?

normally we say current flows from positive to negative. But in reality current comes from the moving of electrons and electrons actually move from negative to positive terminal.

Wait why are you squaring current when finding the power from the battery? Isn't it just P= I x V?

P3 = V x I (24V)(3A) not (12V)(3A) = 72W .. this was almost like a test of comprehension here..
