    F=BIL Relationship with coils Explanation?

    Homework Statement There's no specific problem here so I'd say this template doesn't specifically apply. I'm doing a piece of coursework investigating F=BIL and electromagnets and I'm having some trouble. I think the issue here is the data that I've collected so bear with me. I've been making...

    Kinetic energy of electron & energy states

    My apologies, I missed that off the end of the sentence (too busy messing with equation formatting controls). But yes, L represents a box within which the electron resides. The question doesn't specifically mention boundary conditions though the previous part of the question said to draw the...

    Kinetic energy of electron & energy states

    Homework Statement Use the relationship kinetic energy E = p^2/2m to show that the energy E_{0} of an electron of mass m in its lowest energy state is given by E_{0} = h^2/8mL^2 Homework Equations E = p^2/2m E_{0} = h^2/8mL^2 The Attempt at a Solution I've stared at this...

    Is there a suitable amplifier for my RF signal?

    Hi, I'm an A Level student at college (take it easy, I'm still very much learning) and I'm currently looking into a small demonstration of resonant inductive coupling, or "Wireless Electricity".. I'm fairly confident with the theory behind it and the majority of the build for it. However, one...
