umm.. hello, anyone?

based on the diagram, the result is like this : is that result correct?

ok, here is the path, P is the green one, and pink line is the path. about this i was doing a calculation with cross product, but i am not sure if this is the right way to do, since so please tell me if i am doing it wrong or not

i am sorry, i really don't understand about your clue...i did try to find another example for a whole week after posting that question here... the possible way i could think of is like this : (2.7-1.4) X ay = 1.3 az A/m but i am not sure if the way i get the answer is right or not...

hallo, anyone?

could you please point out which is wrong on my current answer?

sorry for the late response, but do you know how to apply your solution to my problem? probably i still have a little understanding for this kind of question...please help

here is the question, don't mind about point (a) and (b) because i have solved them already...the main problem is the question on point (c) : so far, what i have done is : H = 2.7*0.1-(1.4*0.15+1.3*0.25) = -0.265 az A/m which is the wrong answer compared to the solution provided from the...

so do i have to find total impedance of the resistor and inductor? about the inductor, do i have to start calculating its reactance by assume its reactance at t=1ms?

yes i have learned that but how do you use that to this problem? i have done what you suggested but i am still unable to reach the conclusion, probably because i don't know how to treat the inductor in that circuit, i hope you would like to help me a little bit more about it

btw how about the inductor? should i make it time-based first : 400 cos (2000t + 90°) and put t=1ms into that equation too? or do i have to find the Z equivalent first and convert it to time based equation?

hello anyone?

i need to get the current or the voltage across the R value...do you mean i have to set everything to t=1ms? for example, I(t=1ms) = 12 cos (2000*0.001) = 11.99V?

could you give me an example?

it is when t=1ms and the answer i made above is for the resistor, could you please point out what it is wrong with my answer?
