    The AnswerUnderstanding Kirchhoff's Laws and Sign Conventions for RL Circuits

    about kirchoff? Homework Statement can anybody explain why we write kirchhoff laws on RL circuit like -Ldı/dt -iR=0 shouldn't it be written like -Ldı/dt +iR=0 Homework Equations -Ldı/dt -iR=0 -Ldı/dt +iR=0 it is about signs and how we know inductans' poles + or -...

    High School Why do two point charges with one being zero still exhibit a Coulomb force?

    ı have 5th edition and its may be different because I am not in u.s.a but figure is showed in gauss law

    High School Why do two point charges with one being zero still exhibit a Coulomb force?

    but ı have seen a figure on serway physics which shows atractive force between neutral and positive charged point charge on page 786

    High School Why do two point charges with one being zero still exhibit a Coulomb force?

    about coloumb? i wonder why two point charge whose magnitude 0 and +q(or smt different from zero charge) exert a coloumb force to one another .formula says there shoud be no force acting to each other(because of multiplication q1.q2=0) but there is an atraction between them . if this force...
