One-cell - S8 Three-cell rectirk 3° ELEMENTARY RADIOGRAPHY At each make and break of the circuit of the primary current,a current is induced in the secondary. The secondary current inducedai ;he break of the primary Hows in the same direction as the current inthe primary, while the current induced at the make flows in the oppositedirection. Thus the secondary is an alternating current; but the currentoi the make is SO much weaker than the current of the break that, forpractical purpose, the secondary may be considered a uni-directional
