TA I meant Problem 2 d) and e) not 1. Do you have them please?
Can you give me the formula then TA please for d) and e) please?
Sorry 03, I think Sylar meant the answer from c) and the capacitor value. I copy the message below: Ah, ok. For d)You have the inductance for answer 2b. And the time for 2c. So. The answer will be 2b*2c^2/2. And for 2f is sqrt(2c*capacitor)*pi/2 can you
03 this was mentioned by Slylar in another thread but did not work for me for f) problem 2: And for 2f is sqrt(2c*capacitor)*pi/2 do you have formula for problem 2) d) and e) please?
SyLaR it does not deliver right answer for d and f. does it mean 2* the answer of b and c? or maybe a bracket problem, could you check please?
I thought this is formula for d) d)U = (L*I^2)/2 ?
SyLaR no sorry, have not figured d) e and f) out. Could you tell me quick with values assocated with I and L?
Thanks !@#$%^&leGum and hmmmm b) worked now with !@#$%^&leGum's great explaination !@#$%^&ver, still have problem with d. d)U = (L*I^2)/2 Here L is the length described as d? and I is the current described in question a)? The result comes wrong with that
!@#$%^&leGum if you have time, could you help with this one below please? b) L = mu_0*((N/L)^2)*V, V = (pi*R^2)*d Is V the epsilon value or calculated by V = (pi*R^2)*d? I put my values in but it does not give right answer.
THanks !@#$%^&leGum, see you tomnorrow!
!@#$%^&legum thanks, I get a) but b) and d) not. b) L = mu_0*((N/L)^2)*V, V = (pi*R^2)*d Is V the epsilon value or calculated by V = (pi*R^2)*d? I put my values in but it does not give right answer. 1.25663706*10^-6*((2079/0.42)^2)*9 V = (pi*R^2)*d does
In b) mu_0*((N/L)^2)*V I don't know which value is L?
!@#$%^&legum, what is L value please? I cannot identify. thanks
THanks !@#$%^&legum, will try it out again and report back. !@#$%^&legum I did not try the first question out with the formula, this was mentioned by another one and I thought it works, just look at my profile under: Thanks lo, can you help with Problem 2?
a)B=meu_0*N*I/l b)L=meu_0*N^2*A//l c)I=V/R d)U=1/2(LI^2) I get only c) right could somebody help me with the values, mine is as following: A solenoid has N=2070.0 turns, length d=40 cm , and radius b= 0.2 cm. The solenoid is connected via a switch, S1, to
!@#$%^&legum, this was mentioned in another thread: d) t=-ln(0.25)*2*R*C could you help with question 2 a, b, c please as I think there is something wrong with the formula or I am making a mistake.
Thanks lo, can you help with Problem 2?
Phy, yes second problem. Unfortunately, I could also not get it. Does someone know the right formula please?
Many thanks Phy! Could you help with this please. This was provide by hmmmm and anonymous but only c) works for me. Did you get this: formula for question 2 a)B=meu_0*N*I/l b)L=meu_0*N^2*A//l c)I=V/R d)U=1/2(LI^2)
What value is U by the way?
Did somebody figure out problem after the first question please? I don't seem to get it with above formula.
a), b) and d) I meant. Help appreciated
Only c) worked for me, I am surely making some wrong with a), c) and d). Did someone figure out with above formula please?
THanks hmmmm, r is the radius b=0.2 cm right?
Thanks guys, what is value A please?
Anyone for the rest please?
Q1_2_4= 300 mm^2
In my case it was 500 guys, just try it.
Thanks guys, did somebody have formula for problem 1 and 2?
Anyone please?
Can somebody tell me what the value of R is? thanks
Thanks hmmmmm for help!
Thanks bobpursley! The first problem does not give right answer, could you tell, if this is the right calculation as 10^22 and the formula was not right. 1400/6x10^24*pi*(6.37*10^6)^2/3*10^8 Is this formula above right?
Thanks regz and simonsay!
Simonsay, is that like this below? I have just tried it does not give right answer and says: Expression or statement is incomplete or incorrect. ANy help please and did someone manage? % Define the coefficient matrix a a = N_AB -1,1,-0.7071,0,0,0 N_BC
Simonsay thanks. Something is wrong with the expression, could you please check? I don't get right answer.
Has somebody formula for HW4_2: Part I?
No problem X10, thanks for it anyway!
gggg, for question 1)f) B_0 what is it the formula? Could you give us the value, as the formula from X10 did not work for me. thanks!
Thanks X10, have same problem like P. I don't get it. is this the formula, my speed case value is:200500000 (8.85418782*10^-12)/(200500000) Is there a mistake with my E_0 value?
Sorry DOnny, I did not have the formula until now X10 provided below for Problem 3, maybe enoiugh time: Part a and Part c: d/dt (l (sin((k lambda)/4-t omega)+sin(t omega)))/k where t=2.4*10^-16; omega=3.83*10^15; k=12775810.12; lambda=4.91*10^-7;l=1 Put
Got it X10 thanks vey much! can you maybe help with Problem 1) f) case 2? I cannot get the B_0 for case 2. A formula and the value, I would be greatful.
Meant value for b) X10 please?
MAny thanks X10! I don't sem to get the result. could you give ,e your value, so I can find an approximation for mine?
Anyone managed Problem 3) b) formula or value please?
DOnny, values might vary you need to make some tries but they are usually around that value. Q3: a)0.197142857148 c)0.197142857148 b)? Q5 b) 0 (-4*E_0)/c E_0/c Q 6: a)0 0 (E_0/c)*cos(pi/1) b)0.0269 c)((2*pi)/8)*10^-10 I think the 8*10^10 is omega value for
1_C:-4.05, -4.05,2.59,6.49 Anyone for HW4_2: Part I?
For B_0 the formula seems to be : E_0/c However, I cannot get the result. can anybody work with this or help?
For B_0 the formula seems to be : E_0/c However, I cannot get the result. can anybody work with this or help?
Did anyone got B_0 correct for Problem 1) f)?
