Referring to the calculations given above, this is equivalent to 1' deflection for every degree of elevation, which amount had to be given towards the higher wheel.
By plotting and averaging he obtained the following results: Ex,cess of Deflection and straining Action of a moving Load over that due to a resting Load.
These arms. are then altered until on raising or depressing the battery key there is no sudden deflection either way of the galvano meter.
The deeper layers lag behind the upper in deflection and the velocity of the current rapidly diminishes in consequence.
He showed that at a certain depth the direction of the current becomes exactly the opposite of that which has been imposed by deflection on the surface current, and the strength is reduced thereby to only one-twentieth of that at the surface.
