    I've got a big confusion about proximal convoluted tubule Please tell me if i'm correct. This is what I think -Sodium ions are actively pumped out from the basal membrane of tubule into the blood capillary -This creates a concentration gradient between the lumen of the tubule and the blood...

    Physics 41...How'd it go?

    thats what i did I=Q/t and Q = CV

    Physics 41...How'd it go?

    it asked for average current, which means we had to use rms voltage
  4. L

    Physics 41...How'd it go?

    but werent we supposed to use the rms voltage???

    Physics 41...How'd it go?

    i used 4 cuz it didnt ask for mean resistance
  6. L

    Physics 41...How'd it go?

    yes!!

    Physics 41...How'd it go?

    but i used 13ms
  8. L

    Physics 41...How'd it go?

    yes Alhumdulillah!! how did u get the value for current?
  9. L

    Physics 41...How'd it go?

    and what about the current, i got it as 1.1*10^-3 i used rms voltage*capacitance divided by 0.013s?!

    Physics 41...How'd it go?

    there were 3 components x,y,z...the atom or watever was moving in x direction which is 1 of the 3 compoents so 1/3Nm<c2>

    Physics 41...How'd it go?

    around 60 for A* maybe and 55-58 for A

    Physics 41...How'd it go?

    4
  13. L

    Physics 41...How'd it go?

    yeah i used 4 cuz it didnt ask for mean resistance or something
  14. L

    Physics 41...How'd it go?

    ohhhhhhhhhhhhh, i forgot to do thatttt, i just wrote the value for lamda!!! :'(

    Physics 41...How'd it go?

    but.. what equation did u use????
  16. L

    Physics 41...How'd it go?

    yeah it was 4 and the rms was 2.83
  17. L

    Physics 41...How'd it go?

    its ok, u'll just lose a mark here and what about the frequency and the average current??
  18. L

    Physics 41...How'd it go?

    my value was 0.75 something like that... i used the equation- x=x0 exp(-lambda*t)

    Physics 41...How'd it go?

    yeah i got that too then :P ok and what about the half-life??
