Electrical Engineering: Ch 6: Capacitors (16 of 26) Given Current, Determine Voltage=?

In this video I will find voltage(total)=? given current.

Next video in this series can be seen at:

You are so much better than my lecturer, and you explained the basics very well!

[EtinaMaduma]

I learned so much in such a short time. Thank you

[uiticus]

Should not the current be 50 amps? You are dividing 100 ma by 2 msec. Therefore the units cancel out. Therefore the voltage for region I should be 100 volts.

Hello Michal!

Chapter 6 Lecture 16 you skipped D the time interval, ((2-5ms)^2)/2. = 4.5ms not 3ms in your equation, making solution as Thank You for All Your Work!

[prasantnair]

The resultant voltage due to a ramp current is what I was searching for. Superb numerical explanation.


AND what would the shape of the resultant voltage graph?

[rashalmmri]

It was really nice Journey with you in this course

[snehamathivanan]

For the second region, initial value of voltage is not zero....

[dave-e]

what i do is, since integration is basically area under curve, for first section area of triangle / c, second part area of rectangle /c, much faster approach

[scienceisinaccordancewithi]

sir thankyou very much it helped me alot.thankyou so much

[davidking]

The answer should be: Region 1= 100v; Region 2= 300v so Vtotal=100+300= 400volts. Thank you.

Professor, I suppose we didn't need to do the whole integration part (in this specific question) as we have a regular figure of straight lines . We have a right triangle and a rectangle . Won't the summation of their areas be our answer.

[misikaro]

I think the second part should be 300V, because it has just 't' instead of 't^2'

[rah]

I believe the units are wrong. Region I: (50mA/msec) *(2 msec)^2 /(2 * 1 micro Farad) = 100* mA *ms/ micro Farad = 100 Amp *sec/Farad = 100 volt not 100 mV Region II: (100 mA * 3 msec)/( 1 microfarad) = 300 Amp -sec/farad = 300 volt not 300 mV

[madeeasy]

Sir, Can I use area under the graph of i-t to find the same values of voltage?

Thanks.

[mpume.dzwane]

Hi! Mr van biezen, good lecture why is t squared?

[ajj]

Sir, how is (100*10^-3)/(2*10^-3) not equal 50.

Thank you
Kind Regards

[majedmalhies]

The question is asking for currents and we found voltages! what do these voltages represent exactly?

[marielle]

how did you get 100mV sir in my calculation its 100V? thanks. :)

[rashalmmri]

I think the result should be 400V not 400mV 🙂🙂

[zanekhan]

For V2 i had gotten 300v how did you get 300mv?
