Nikola Tesla - Free-Energy Devices

108 INVENTIONS OF NIKOLA TESLA.in poles A by the primary impulse. Tins condition is indicatedby the characters N' s'.In the circuit formed by the two sets of coils F and G is introduceda condenser H ;otherwise this circuit is closed uponwhile the free ends of the circuit of coils E are connecteditself,to a source of alternating currents. As the condenser capacitywhich is needed in any particular motor of this kind is dependentupon the rate of alternation or the potential, or both, its sizeor cost, as before explained, may be brought within economicallimits for use with the ordinary circuits if the potential of thesecondary circuit in the motor be sufficiently high. By givingto the condenser proper values, any desired difference of phasebetween the primary and secondary energizing circuits may beobtained.
