Physics 13.4.2e - Parallel Circuit Example

[findingtime5]

Thank you so much..I've watched most of your videos with having little knowledge in this area for my physics 2 class and am up to par now because of these videos. All your videos make everything so easy to understand. Very much appreciated. Your method of teaching is awesome, I just wish everyone taught like this. Thanks!

[samanferrari]

is there a difference between voltage and voltage drop?

[Midgetman303]

@samanferrari There shouldn't be. The voltage drop should equal the sum amount of the voltage that is applied through your power source. (or battery)

[therealjordiano]

thank you so much :D

Nice video. Thank you!

Khan academy doesn't cover this. and u have better software =]

[abawi192072]

u r the best teacher.........

When you say V = V1= V2= 120V. I find it little confusing, because V1 is a voltage drop at R1, similarly V2 is voltage drop at R2. So, according to the previous explanation, the total V= 120 V=V1 + V2. Like you said before the voltage drop is same in V1 and V2. But, I am unable to understand, how come V1 and V2 individually is equal to V. Please explain. Thanks.

@dnandy100 120V would equal V1 + V2 if the two were in series. If they are in parallel, then V1 and V2 each equal 20 Volts. In parallel, the voltages are the same. In series, the voltages add up.

Does anyone happen to know the name of the hardware used to produce this tutorial?

[KevinBarbossa]

so does this mean that for all examples i could skip the arithmetic for total amps in the last part and jus add the the number of amps i calculated at the beginning when i solved for I (current)

[derekowens]

@KevinBarbossa If everything is in parallel, yes, if I understand your question.

[macwhite4265]

V/RT=8

[macwhite4265]

R1xR2/R1+R2= 15

[andersonlavor]

Use the windows calc ( Reciprocal key is on top of = key)

do like this:

type in the resistance 60 ohms press the key reciprocal 1/x which becames 0.01666.... then press + and type 20 ohms then reciprocal key 1/x it becames 0.05 then press equal = that results 0.0666666... then you press reciprocal key 1/x again and boom there it is ... 15 ohms

[derekowens]

@andersonlavor very nice!

[andersonlavor]

hehe,,, I just know,,, using reciprocal calc,,, the number 15 ohms match... LOL

At 2:40 i got stuck with where you got 3 over 60 from D:

[OriginalAtomicSheep]

are you sure you explained it the right way around? Your battery is connected with positive terminals pointing down?

[mark94uk]

UR AMAZING OMG I WILL PASS MY PHYSICS AS ONLY BCOS OF YOU LMAO :D sub

[egeovannyam]

what is the name of the software using to present this?

[starced87]

im going to use you as my tutor! feels like I should be payin you. i appreciate it, I really mean that.

[hannahfageeh]

such a good explanation! :D

[kristinealivio]

cool

[kristofferinus]

thank you..only now i know this..

[texasmacman]

That was great. Helps me understand what is going in my classroom a little bit better.

[LauraJustine81]

<333

you teach me physics better than my teacher

[ndguggen]

fantastic explanation, man.

[jackhammer250]

Where did the the 3 and 4 come from. you through me off with that step? . 1\3 + !\4 By the way im taking Electronics basic D.C

[derekowens]

I don't think the 3 and the 4 were in the denominators. They were in the numerators when we were making the fractions into equivalent fractions with a common denominator of 60.

[sumeke911]

if you work out the 1/20 + 1/60 the common mulitple would be 60 and 60 into 20 goes 3 so its 3/60 and 60 into 60 goes 1 so its 1/60 then you add the numerators 3+1= 4 and put back the denominator 60 and you get 4/60

[yamahabibi]

Beautiful explanation and thank you very much for this video ...

10 out of 10 .

thanks

[Johnjpcoc]

Every time Im watching u vedio,, I have to say something bad to my teacher!!!!

Can't help it!!!!! Sorry I hate her!!!

:D

[BRADD500]

i wish i was as clever

[nightmathzombieethan]

Yes,THANK YOU!

[Sinanthir]

Thank you so much...you're helping me understand my homework. XD
