Thise electrode is the cathode.
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
To keep your chin up is an expression to maintain positive outlook.
You will want to connect them in "parallel" (positive to positive, negative to negative). If you connect them in "series" (positive to negative) you will add one voltage to the other, making 24 volts.
To get 24V from 2 12 V battery's Yo hook up the positive pole + of one of the battery's to the negative pole - of the other one. you will be left with a positive pole on each battery wit no connection on them The voltage between them is 24. If you want the battery to have the same voltage but have more amperage you connect positive to positive and negative to negative.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
In a zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
We find carbon or graphite as the center electrode of a zinc-carbon battery. It's the "common" battery we use in lots of stuff (but not an alkaline battery). That center electrode is the positive one, and the zinc makes up the outer or negative electrode in this battery. In an alkaline battery, manganese dioxide is the center, or the cathode (positive electrode). Powdered zinc will be found as the outer or negative electrode (anode).
Electrolysis.
Because if DC is used, solution undergoes electrolysis and the products of electrolysis set up a back emf which opposes the flow of current -s
If you are referring to the small unusable piece of welding rod that is left after welding, most call it a electrode stub.
It is inverse: electrolysis separate elements.
A lead acid battery produces oxygen bubbles and hydrogen bubbles when it is being charged. A way to use this principle is to use two electrodes (pieces of metal) seperated from each other in the water. Then hook them up to a source of direct current (DC) electricity. You need to connect the positive to one electrode and the other to the negative. When the electricity is applied hydrogen bubbles will form on one electrode and oxygen bubbles on the other. These could be trapped in a flotation bag to lift the ship. It would take a massive amount of electricity to produce enough bubbles to lift a ship but it would work.
The answer is electricity
They are often used to manufacture things, such as sodium from salt. Another example is the breaking up of nitrogen oxides in a catalytic converter.
500 electrons per second, exactly.
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
electricity... :P
