i = q/s and q = is
q = 31.6amps x 2.16 x 10-7 s
q = 6.8x10-6 coulombs
If
100 watts is assumed for the detector circuit, the current at
50 ohms is:
I = square root (100/50) = 1.4 amps
and the charge:
q = 1.4 amps x 2.16 x 10-7 =
3 x 10-7 coulombs
Using
Coulomb's law to calculate the force on each charge separated
by the given distance:
F=(q1q2)/(4p e 0r2)
F=(3x10-7)(6.8x10-6)/(4p (8.9 x 10-12)(6.4x104)2)
F = 4.5x10-12 nt. = 4.5x10-7 dynes
Assuming, finally, that the detector circuit uses a 100 microfarad capacitor,
the force of the field will result in a voltage as such:
e = square root (F/(C x 107))
e = square root ((4.5 x 10-7)/(100x10-6x107))
e = 21 x 10-6
A change of 21 microvolts would be well above the 5 microvolt
level required for a radio receiver to capture a signal from the
electrostatic detector circuit. It should be remembered, too,
that Tesia worked at higher energy levels than used in this example.
He used hundreds of amps at lower frequencies(more charge) and potentials of millions of volts.
This analysis of Tesla's wireless transmission
method is preliminary, but does indicate the type of field of
force and distance calculations that have to be made in order
to have a successful electrostatic communication system. Issues
dealing with the optimum frequencies, the earth as a dielectric,
and the function of the earth's charge in power transmission
have to be investigated. This is in addition to the questions
yet to be discovered. However, it is clear that 100 years ago
Nikola Tesia began a branch of communication technology that
differs significantly from that in use today.
