What is the difference between a telegraph and an electrochemical telegraph?

A telegraph is a device for sending messages ("graph") over a distance ("tele"). Smoke signals sent by Native Americans qualify under this definition. So does the use of flags or signal fires. An electrochemical telegraph suggests that an electrochemical device, like an electrochemical cell or set of cells -- a battery -- is used to power up a system that transmits those messages.
By making and breaking an electrical circuit with a telegraph key, a solenoid on the other end can be made to "click" and be heard. All that is required is a system of "code" to transmit characters from one point to another down a telegraph wire between the key and the solenoid. The battery provides the power.
By using that same electrochemical source, a light could be powered up using the key. With the light and the same code used in sending messages over a wire, an individual could communicate between two points without a wire. Ships at sea could communicate with that light (though they usually use ship's power instead of a battery), or two scouts on a camping trip could communicate silently across a broad valley using flashlights.

Where do chemical reactions occur in electrochemical cells?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell.
What is an electrochemical response?
An electrochemical reaction is any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances.
Can the metal plates in an electrochemical cell be made of the same metal?
Historically, no, each metal has its own redox potential and it is the difference between them that causes the flow of electrons with the electrolyte carrying the charge in the cell and the circuit between the metals that carries them outside the cell. However, there are now cells that do not use the metals to create the electrochemical potentials where the metals are only conductors wherein the metals are where the electrochemical reactions take place, but are not reactants. These have to have a membrane between the two reaction compartments to keep the two reactants from reacting in solution or in the gaseous state. These are more often referred to as batteries in my opinion, or as fuel cells.
The anode in an electrochemical cell has this charge?
The Anode in electrochemical cell has negative charge (-ve).
What tissue connects electrochemical impulses?
Nervous tissue contains cells that send and receive electrochemical signals.
What are the difference between LCR meter and electrochemical impedance spectroscopy?
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
What is the difference between telegraph and telephone?
The difference is it take wire less reciver
Difference between galvanic series and electrochemical series?
Electrochemical series-The position of a given metal in electrochemical series is fixed.there is no info. regarding position of alloys.it tells the relative displacement tendencies.Galvanic series-position may shift.alloys are included.predicts relative corrosion tendencies.

What is the difference between diffusion and active transport refer to cell membrane and its properties?
Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
What is the difference between buying TT and buying OD?
TT is telegraph transfer and OD is on demand.
Where do chemical reactions occur in electrochemical cells?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell.
Whats the difference between the telegraph and the cell phones?
A telegraph relies on a wire to transmit a message to an individual on the receiving end. A cell phone is a wireless device that uses radio waves to transmit a signal.
What is the difference between telegram and a letter?
The difference between a telegram and a telegraph is that a telegram is a message communicated through delivered in written or printed message from while a letter is written or printed message usually in envelop sent by post.
Where does the telegraph come from?
The first working electrostatic telegraph was built by the English inventor Francis Ronalds but its origins go back much farther to pre electric versions (hand signals by sight which has nothing to do with the machine but same concept) and electrochemical-where electricity alone was not used in the design
What is the main difference between active trasport and passive transport?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
How was early radio different from early telegraph system?
The difference is the telegraph required wires; the radio did not. But other then that, they were mostly the same.
