Electric Transmission – The Invention of Electricity and Evolution of Voltage

Everybody knows how electricity was invented. Famous scientists like Antonia Anastasio, Benjamin Franklin, Luigi Galvani etc contributed with their theories and experiments. We can see the time line here:

  • 6th Mar, 1650: Thales of Miletus — Static Amber
  • 7th Mar, 1752: Benjamin Franklin — Lighning Rods
  • 7th Mar, 1752: Benjamin Franklin — Kites and Lights!!!
  • 1st Mar, 1786: Luigi Galvani — Muscle Moving Energy
  • 6th Mar, 1800: Alessandro Giuseppe Antonio Anastasio Volta — Voltaic Pile (Electric Battery)
  • 9th Jul, 1876: Alexander Graham Bell – Telephone

But, did someone ever wonder about the evolution of concept of Voltage? I guess very few of us knows about it. Here is a unique and differentiating info graphic depicting the Evolution of Electricity and the Journey of Voltage. It’s very important for all of us to know what set of events led to the current scenario of Voltage in the electric appliances we use at present, how voltage converters and transformers, dual voltage devices came into existence.

ATLONA AT14042 HDMI FEMALE COUPLER 110 VOLTS USE ONLY IN USA

index

The Atlona AT14042 HDMI Female Coupler couples two male HDMI cables together, and is designed to prevent signal loss in the connection.

To make full use of the extra space inside the adapter, 18 gauge wiring is used instead of 26-30 or Atlona’s previously used 24. Such thickness allows a transfer signal with no loss.

Additionally, top quality materials are used, such as 99.99% Oxygen Free Copper (OFC) conductors and triple shielding technology. The OFC conductors have a silver plating with ultra high conductivity, very low signal loss and degradation, low electric resistance, and great signal transmission. The triple shielding technology rejects EM and RF interference.   24k gold-plated connectors ensure a great connection and a very tight grip.
