. The widthof the groove is to be divided by the number of turnswhich would fill it, to find the average diameter (ha,or jky of the wire. Subtracting tliis from the out-side diameter (hk) we have the mean diameter (jy, or ce) of the coil. Dividingby 2 we have the mean ra-dius of the coil. Instead… … 446 ELECTEICAL CURREJfT MEASPKE.
