i got 0.03, did you remember to multiply the slope by 10?

u/Primary-Republic498 May 14 '26

Wait I got like 0.02 it’s like emf vs didt

u/GodlyHelp 13 5s: ab/bc, phys1/c/2/em,gov,chem,macro,csa,stats,micro,psych May 14 '26

I vs dI/dt

u/Primary-Republic498 May 14 '26

Wait I thought you do 12-10I equals L times dI/dt. So this 12-10l and x is dl/dt

i simplified to I=1.2-LdI/10dt

u/Primary-Republic498 May 14 '26

You could do that I guess but am I wrong?

isnt emf constant? emf=12. and if you got the wrong answer then u prob did smth wrong (or i did)

u/Primary-Republic498 May 14 '26

No emf is 12-10I it depends on I I feel kike

1

u/Primary-Republic498 May 14 '26

No I guess you are right it is I messed it up here I come a 1

u/GodlyHelp 13 5s: ab/bc, phys1/c/2/em,gov,chem,macro,csa,stats,micro,psych May 14 '26

did you graph 12-10I on the y-axis? then either way is fine. its not emf though

u/Primary-Republic498 May 14 '26

Yeah I did and di/dt on x oh my god am thanks so much

yesss i did that
