    That means that during charging and discharging the the currents decays/decreases in both cases.??

    Hubble's Constant can be easily calculated (fixed exactly) using ONLY the speed of light (C) and Pi 2 X a megaparsec X C, divided by Pi to the power of 21 = 71 K / S / MPC. This equation comes from the "Principle of Astrogeometry". Ho is fixed at 71. No tension, no waffle required, just simple algebra.. David Hine

    My textbook uses sin instead of cos. How do I know which one to use and when?

    • @JosephBidenator
      @JosephBidenator 5 месяцев назад

      the cos is used when the area and the magnetic field lines are perpendicular to each other, and we take the normal to the area, and we compare the normal line of the area to the magnetic field lines.
