    Impedance of Coil - Why Does Impedance Increase?

    @Averagesupernova: i agree with you. i just wrongly interchanged impedance (R + jX ohm) with reactance (jX ohm). sorry.

    Impedance of Coil - Why Does Impedance Increase?

    ok ok. i understand what tc_kid, Averagesupernova, and NoTime. thanks for the correction. as indicated in my first post, i am still a student.

    Impedance of Coil - Why Does Impedance Increase?

    1. There is no such thing as a capacitance of a coil. A coil only stores energy by means of the magnetic field (hence, the coil exhibits what is called inductance). A capacitor, in the other hand, stores energy by the potential difference between its plates, which is in turn caused by the...

    Impedance of Coil - Why Does Impedance Increase?

    https://www.physicsforums.com/showthread.php?t=195357 i would like to share some ideas. i agree with ranger. increasing the cross-sectional area of the WIRE will decrease the DC resistance of the coil. R = ρ*L/A ρ = resistivity of the material used for the wire L = length of the wire A =...

    Exploring the Physical Meaning of Line Integrals

    hello. the prime application line integral is to calculate the work done on a particle on a force field (usually given by a function F(x,y,z)). for every infinitesimal movement of a particle BY AN EXTERNAL AGENT, there is the work done by the external agent to somewhat "negate" the effects of...
