If you have a 110 volt direct lighting current in your home instead of 110 volt alternating current, then you will also need an electrolytic interrupter, for in this case the primary circuit of the transformer must be made and broken rapidly in order to set up alternating currents in the secondary coil. The Alternating Current Transformer.
Arcot stepped up to the controls and closed the switch. The lights dimmed a bit, but immediately brightened again, and from the other end of the room came a low, steady hum as the big transformer took up the load. "Well, from the sound of that ten K.W. transformer there, if this engine is very efficient we ought to get a terrific amount of power out of it." Dr.
The Rotary Spark Gap. In this type of spark gap the two fixed electrodes are connected with the terminals of the secondary coil of the power transformer and also with the condenser and primary of the oscillation transformer.
Such bits of testimony from painters help us to understand the brief sayings of the critics, like Taine's well-known "Art is nature seen through a temperament," G. L. Raymond's "Art is nature made human," and Croce's "Art is the expression of impressions." These painters and critics agree, evidently, that the mind of the artist is an organism which acts as a "transformer."
Next connect the posts of the secondary coil to the posts of the rotary or quenched spark gap and connect one post of the latter to one post of the condenser, the other post of this to the post of the primary coil of the oscillation transformer, which is the inside coil, and the clip of the primary coil to the other spark gap post. This completes the closed oscillation circuit.
The simplest kind of a wireless telegraph transmitter consists of: a source of direct or alternating current, a telegraph key, a spark-coil or a transformer, a spark gap, an adjustable condenser and an oscillation transformer.

The Alternating Current Transformer.
Finally connect one end of the tickler coil of the tuner with the plate of the detector tube and connect the other end of the tickler to one end of the primary coil of the first audio frequency transformer and the other end of it to the wire that connects the two B batteries together.
The whole of the high tension wiring is placed within a small space so as not to endanger the pilot, while the transformer is hermetically sealed in a box with paraffin. The aerial comprises a trailing wire 100 feet in length, which, however, can be wound in upon its reel within 15 seconds.
A rotary gap with a 110-volt motor costs about $25.00. A quenched spark gap not only eliminates the noise of the ordinary gap but, when properly designed, it increases the range of an induction coil set some 200 per cent. The High Tension Condenser. A condenser of this value for a 1/4-kilowatt transformer costs $7.00; for a 1/2-kilowatt transformer $14.00, and for a 1-kilowatt transformer $21.00.
