The electrophorus cover, E C (No. 42), furnished, is a tin box with a fancy top.
These instruments are the electrophorus, the condenser of electricity, and the doubler of it.
Well, next after the electrophorus comes the "fire syringe" (Fig. 7).
The electrophorus consists of an insulated conducting plate applied to an insulated electric.
The theory of the electrophorus is very simple, provided the student has clearly grasped the principle of induction.
The electrophorus (e-lec-troph-o-rus) is about the simplest form of machine.
To use the electrophorus, the ebonite is given a negative charge by striking it with fur or flannel.
If you do not get a good spark from the electrophorus, read the directions again.
The Insulating Table consists of a tin box (exactly like that used for the electrophorus cover), and an ebonite rod about 1¾ in.
The electrophorus (Fig. 34); a pin, bent slightly to keep it from rolling.
An electrostatic generator, constructed like one half of a large capacitor, the other half being any grounded surface, such as a table. A small charge is given to the electrophorus when it is near the grounded surface, effectively charging it like capacitor. As the electrophorous is lifted away from the surface, its voltage relative to the surface increases (as the capacitance decreases).
