| Description |
English: A better diagram of an experimental spark transmitter. This circuit is quite different from the circuits of practical spark transmitters used during the early 20the century. The battery would need to have a potential of several thousand volts to jump across the spark gap, and the circuit only produces a single spark when the battery is connected. |
