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.
