    Physics: Post your doubts here!

    I think I've attached the file; it's how I draw for no 5aii.... I recommend that you take readings for R=2 (Would give I1=1.5), R=6 (Would give I1=1) though.

    1b. Use formula R=(p*l)/A (p is resistivity, l is length, A is cross-sectional area of wire, use formula A=pi*(0.5*d)^2 R is resistance) So you just input the original measurement into the equation. 5a (ii) Okay so you've found 0.667 for the minimum current. So you can draw a curve with...

    Awwww..... I got the complex number wrong for the second part... I thought I also got the differential equation wrong... :( (I think I got x=0.5 instead of 100/57)... As I said before, I also got wrong with the trapezium rule (I mistakenly thought the area was above the graph!!), and also the...
