Italian scientist Alexander Volta in 1775 gave the electrophorus the form which it retains to the present day.
This Volta electrophorus, and these three blackboards, will serve for the purpose.
I first excite the electrophorus in the usual manner, and you see that it then influences a charge in its top plate; the charge in the resinous compound is known as negative, while the charge induced in its top plate is known as positive.
Of late years the principle of induction, which is the secret of the Leyden jar and electrophorus, has been applied in constructing
These tiny sparks from the electrophorus, or the bigger discharges of an electrical machine, can be stored in a simple apparatus called a Leyden jar, which was discovered by accident.
When the charged plate or conductor of the electrophorus touches the knob the inner foil takes a positive charge, which induces a negative charge in the outer foil through the glass.
My Thursday was drawing to a close; I had to return to Avignon, to resume my lessons on the electrophorus and the
