My teacher never bothered explaining efficiency and giving an example and then a problem to us, to see if we understood. Instead she wrote a shitty example of efficiency on the board and told us to write in our notes and bam that's all. Now I have it on all my quizzes not fully understanding it. Thanks to this video, I get it
Thanks muchly! Being a Triple Science student, I felt a bit stupid for not knowing how to calculate the efficiency of something. But this video helped so much and now I feel confident for my test tomorrow on biomass and pyramids of biomass. I am very grateful, cheers Mr. H!
Have a science exam tomorrow, in year 8 and needed to know how to calculate energy efficiency cause i totally forgot from class. Works like a charm, thanks a lot .
I usually prefer to state efficiency as , Efficiency = Useful work/ input work, the answer will be in decimal. Some of my students get confused especially when the efficiency is given and other parameters were asked to be determined. If they get the value of Eff to be 0.7, i will just ask them to multiply it by 1, they will shout that the answer is still 0.7, i will then say instead of writing one directly, we will replace that 1 with 100/100.
i dont know why.. but efficiency is actually power output divided by power input.. its not about total etc... and u r completely wrong , the symbol for efficiency is not e... it is denoted by etha.. which represents the english"n" alphabet
+Astrogoals tutorials yeah i've got one tomorrow, just stay calm and focus and don't panic, all that stuff, if you remember the equation by heart it should be ok :-)
Miledown brought me here. BEST MCAT deck ever!
did it have your mcat score?

Same
im in the same situation

"Thank You", thank you very much. Your presentation was direct, efficient and simple to follow and understand 😎
I studied this for so long and it only took you 4 mins thank you so much 👍🏿
I havent been able to understand efficiency equations yet. You have helped me slightly. Thank you !
You teach so well Everything is clear slow and Understandable i wish you were my teacher.
Have a science exam tomorrow, in year 8 and needed to know how to calculate energy efficiency cause i totally forgot from class. Works like a charm, thanks a lot
.
THANK YOUUUU !! my exam is in half an hour and it at the library watching this video I was gonna fail omg thank uu.
How'd it go?
excellent
why is this so me right now
Thank you! This makes much more sense now. The way you explained it was 10/10
this helped heaps for my exam thank you!
Oh my gosh, I have Chronic Fatigue Syndrome so I can't go to school. You have done better then my teacher, thanks so much.
wow, this is amazing.. i never thought that calculation would be this simple.. thanks
oh my gosh. thank you so much!!! you saved my life! hopefully i pass my physics exam
you saved my life some much man, thanks you are the man.
Wow your explaination is so good it throw away my quiry
thanks a lot I have a test tomorrow lmao
mate thank sooo much man i am really thankful to u i have a test tomorrow and guess what smart-me did
, chose to study 1 day before u save me
Thanks mate.... Really helped me out with my science homework😀
in year 8 totally clueless thanks for telling what i already know
This is soo helpful since im learning and i have an assignment
thank you mate you really helped me out here
you're doing god's work son.
Thank you so much this was a very useful tutorial!
who else got confused when in other places it said to multiply by 100% rather than 100.
I did. because 100% is 100/100.
Thanks MrHuxley.

thank you, this helped a lot with my homework
Very help full information.
"Thank you"; you will understand the lesson 100% and it will not take time from you.
That’s really helpful! Thanks!
Thank you very much this helped me alot.
Thank you!! This video was very helpful
What if the only available is voltage, current and hp output? How can i get the input
very useful for my exam tomorrow
Thank you so much!!! It is helpful!
Thanks for the help it was very useful
This video is perfect
What is you don’t have the useful or wasted energy but only had the GPE
if the gave us the efficieny and the useful energy and told us to find the total energy. what are we going to do
i honestly thank you very much
thanks man this helped a lot
Thank you
Kinda Confused.. I'm 13 in physics. Our paper says "Efficency=(Wo/Wi)×100.. how do I tell the difference between the input and output
+Felix YomampApa He used energy for an example, im pretty sure thats just watts out and watts in. Same thing
+Nathcor Lol after i typed that I felt like such a dumbass
Felix YomampApa lol :')
please confirm how to calculate the energy of 3 watt cfl bulb
Thank u mr.H
Legend cheers 👌
i dont know why.. but efficiency is actually power output divided by power input.. its not about total etc... and u r completely wrong , the symbol for efficiency is not e... it is denoted by etha.. which represents the english"n" alphabet
Thanks
I can finally do my homework lol
2020?
got test on tuesday can anyone help
+Astrogoals tutorials yeah i've got one tomorrow, just stay calm and focus and don't panic, all that stuff, if you remember the equation by heart it should be ok :-)
+Will Midgley cheers m8
Im saying this 2 years later but good luck😂😂
Astrogoals tutorials hmm
Astrogoals tutorials it’s been 4 years so I can’t help
helped
👍
This video is as old as I am lol
Do my homework lol 😂😂😭😭😭
I don't get it
why Science has math in it
duaa awt ikr... I'm good at math tho
good for u..
sofia xox because science wants to make us suffer
I’m doing this as religion study home work 😒
What the hell
why does nothing make any sense??????????????????????????????????
Thanks
