    Why Does an Inductor Store Energy After No Current?

    I calculated all the required in this problem correctly but can't understand why the sum of energy extracted and absorbed is not zero. They are: >0: 0J 0 <=E<=25: 4t^2 J 25 <= E <= 50: 4t^2 - 0.4t + 10 * 10^-3t J E > 50: 0 J Does that mean that an inductor stores energy even after there...

    Inductor Efficiency: Does it Produce More Current?

    I think yes but will there be loss of energy between the conversions that take place magnetic field to current or vice versa? Thank you

    Inductor Efficiency: Does it Produce More Current?

    I think from the equation I can say that it depends on the inductor's coefficient itself. Am I correct?

    Inductor Efficiency: Does it Produce More Current?

    Hey everyone, I am taking a circuit 1 course in college and was wondering if an inductor is actually efficient. What I mean is that does it produce more current than the current already supplied. I know it keeps the circuit going even after the voltage source is cut, but does that mean that, if...

    Determining the voltage polarity of the independent current source

    if I am going through the positive terminal of a component, I will write P = +V I if I am going through the negative terminal of a component, I will write P = - V I Isn't that correct?

    Determining the voltage polarity of the independent current source

    It would make a difference if I am calculating, for instance, the power developed and dissipated

    Determining the voltage polarity of the independent current source

    Thank you so much for replying I did so and got -5 V (with that number how can I determine the positive and negative ends of the current source's voltage?)

    Determining the voltage polarity of the independent current source

    I am so sorry if I am posting this in the wrong forum; it is just not a homework problem, and I can't find the right place - it's more of a study help question.

    How Can Visualizing Magnetic Forces on Current Enhance Understanding?

    Yes, I understand now what is happening Thank you so much for clarifying; after the first couple of questions, all involved a triangular arrangement I thought these questions can't be solved without the cosine law! Thank you so much again for clarifying

    How Can Visualizing Magnetic Forces on Current Enhance Understanding?

    does it give that answer if you do so? if Yes, can you tell the difference between this question and that question, please: Three long, straight, parallel wires each carry a current of 10 A in the positive x-direction. If the distance between each wire and the other two is 10 cm, what is the...

    How Can Visualizing Magnetic Forces on Current Enhance Understanding?

    Aren't those wires parallel, and the length is 50 cm?

    How Can Visualizing Magnetic Forces on Current Enhance Understanding?

    hey, thank you for replying to my question If I put them that way they won't give 1.5 mT and I don't think we can use the cosine law in that case

    How Can Visualizing Magnetic Forces on Current Enhance Understanding?

    This is how I visualize the problem (of course I am drawing this as if it is in the z-y axis); I don't know what will be the next step. Anyone please help me. Thank you

    Particle in a circular path due to magnetic field

    Oh, I see what I've been doing Thank you and sorry for taking too long

    Particle in a circular path due to magnetic field

    Thank you but if I did this to convert ev to j sqrt(2 * e * (3000e) / mass) <---- where e is the charge of a proton and 3000e is the ev to joule conversion I get the wrong answer
