Although previous transmitters were bulky and the spark gap system of transmission was difficult to use, there had been some earlier attempts. Source: Internet
An AC voltage from a high voltage supply transformer charges a capacitor, which discharges through the spark gap. Source: Internet
A typical high-power spark gap was a rotating commutator with six to twelve contacts per wheel, nine inches (229 mm) to a foot wide, driven by about 2,000 volts DC. Source: Internet
Depending on how the spark gap is set, usually one or two sparks occur at the peak of each half-cycle of the mains current, so there are more than a hundred sparks per second. Source: Internet
Each spark across the spark gap produces a pulse of damped sinusoidal high voltage at the output terminal of the coil. Source: Internet
