14. This coefficient remains to be determined 16. Here we use two metal balls two meters apart. o The primary winding of a transformer is the coil which is fed with an alternating current, and lor: while the secondary winding is the coil 2 to which power is transferred via the changing flux. The designations of the primary and the secondary depends only o how the transformer is connected; either winding may be the primary, and the either is then the secondary

14. This coefficient remains to be determined. 16. Here we use two metal balls two meters apart. ① The primary winding of a transformer is the coil which is fed with an alternating current, and [or: while] the secondary winding is the coil ② to which power is transferred via the changing flux. The designations of the primary and the secondary ③ depends only o how the transformer is connected; ④ either winding may be the primary, and the either is then the secondary
