Homework Statement A straight wire of electric charge truncate to length L has a linear charge density of ρ= 8 C/m. Using a computational approach calculate the electric field due to the truncated line at any arbitrary point in space. Consider L = 1 m, assume line lies along y-axis with...

so when does the equation for conduction comes in? how is induction related to conduction? what is the difference between power delivered by conduction and power delivered by induction?

when they state power transformed, are they referring to the power delivered at by induction? therefore they use power conducted - power transformed = power conducted??

Homework Statement Upon finding my max. rated output power, and after finding the power transferred by conduction, can i just use: Output power - power transferred by conduction = to get my power transferred by induction? or do i have to apply the formula where, S = E1I1 = E2I2? The...

can someone please tell me how did they derive with the above equation? my point of view: Vgs = Vin Vds = Vout so how did they even get Vgs = Vds? below shows the Small signal circuit: might be a stupid question to ask. but i am really confuse on when to look at the original circuit, when...

Homework Statement i am able to derive out node B and node C, but got stuck at node E. Can somebody please help me out with it? Homework Equations node analysis The Attempt at a Solution i used microsoft to show you my steps as there are too many subscript.

Electric Field inside a closed gauss box. Homework Statement there are +2uC and -2uC charges inside a close "Gauss" box. Which of the following statement is true? Homework Equations given option are: 1) the net electric flux through the box is zero 2) the electric field is zero...

ok. thank you.

it does make sense, and i did the working using KE1 + PE1 = KE2 + PE2+ W but was confused when i saw this

wait wait... i got confused again. the equation is: KE1 + PE1 + W = KE2 + PE2 OR KE1 + PE1 = KE2 + PE2+ W

ok... thanks a lot. FYI: i am an electrical student, and i have no idea why am i learning this. struggling in my circuit though. =(

I get it now. just to clear some doubts, work done BY system = positive work done ON system = negative - the signs are fixed regardless of direction? for example, if i were to exert a second force of 100N on block B downwards or upwards, since it is work done ON the block, it will be a...

KE1 + PE1 = KE2 + PE2 + Work done by/on system 0 + 33.354 = KE2 + 98.1 (from previous working) work done by/on system: since the force is towards the right: + given force + block A - Block B (string tension) - friction = 200 + 33.55 - 98.1 - 27.66 KE1 + PE1 = KE2 + PE2 + Work done...

i think the problem with this question for me would be getting the initial potential energy. here is my working: total initial energy = total final energy 1/2mv^2 + mgh = 1/2 mv^2 + mgh since system is at rest initially, 1/2mv^2 = 0 total initial potential energy = mgh(a) + mgh (b) =...

attempt using Newton's law: F = ma = 200-27.66+33.55-98.1 (these 3 values are taken from the force that i had calculated in the previous parts (i)(ii)(iii)) 20a = 107.79 a = 5.3895m/s^2 v^2 = u^2 + 2as v = 3.28m/s K.E. = 1/2 mv^2 K.E. = (0.5)(10+10)(3.28)^2 = 107.79J is that correct?
