I1=0.5 A

Never mind. I solved it. Thanx for reply anyway.

Yup, my error. Anyway, after looking at problem again I solved it in different way. I think this way makes more sense (at least to me). Previous solution did not count ). So, can you tell me whether this one correct? I2 = current over R2 a=100/1=100 I2=aI1 V2=V1/a V2 = (-I1R1+E)/a V2 =...

Homework Statement Can someone inform me wheher my solution is correct? Homework Equations V1 = E2 * (10^-3)/2*(10^-3) = 0.001 V2 = E1 Ra = (R2+R3) = 0.02 Rb = R1 = 30 n = (1/100) n^2 = (1/100)^2 The Attempt at a Solution I1 = (V'1 - V2)/(Ra'+Rb) I1 = (0.001/n - 230)/(0.02/n^2 + 30)...

Hello?

Homework Statement Homework Equations E=100 kV/m E=cB B = E/c B=(100000/2.998*10^8) B=0.0003335557 m = 10g = 0.01kg A=0.5mm^2 = 5*10^-7 m^2 I = (EB)/(4п*10^-7) = (100000)(0.0003335557) / (4п*10^-7) I = 26543519.23 The Attempt at a Solution a) Pressure = I/c =...

So, final answer sould be: =((H1-H2)(B2-B1))*f =-60 * 50 =-3000 j sec^-1 m^-3 Makes sense. Thanx for help :)

So, it sould be something like ((H1-H2)(B2-B1))*f ? Where did I go wrong with units? Is it j/m^2 due to area (not volume)?

Homework Statement H1=10 H2=-10 B1=1.5 B2=-1.5 Homework Equations (change)Uloop = (change)H2*B2 + (change)H1*B1 The Attempt at a Solution =(H1-H2)(B2-B1) =(10-(-10))(-1.5-1.5) =-60 j/m^3

Homework Statement Greetings. Can someone give me hint how to solve following problem: Homework Equations From my understanding, you need following formula to solve problem: and then potential can be obtained by integrating over the current distribution. But right now these foormuas really...

No, just screensot from unknown book our lecturer send us before goin to easter holiday. No details,sadly. Anyway, since google does not find anying about Lorentz’s law of voltage it can indeed be a typo. However, from what I can see, Lenz's Law = E=-N (dФ/dt) or emf = -(loopsofwire)(magnetic...

I don't know. I suppose that is possible, since I never heard before about Lorentz’s law of voltage.

Homework Statement Greetings So i was trying to solve following prolems: Homework EquationsThe Attempt at a Solution I did manage to solve problem 22 using E = NAB(2pi * f) E = (100)(0.005)(0.9)(2pi)(50) = 141.372 v But I have no idea what to do with problem 21. Mostly because I don't know...

Thax for reply, so, all I need to do is to find final vector considering both positive and negative charge of segment? In that case I assume that charge vector should point directly downwardat point x, is that correct? Also, dE mean electric field vith certain direction (vector) and not...

Hi, I was given following problem to solve Now, I am not looking for solution, but i would appreciate if someone explain what exactly they are asking me to do (is this about finding final charge vector? or is this about gaussian surface, I am new at electricity and magnetism so I am...
