platinum
Lead
Various elements are used for making electrodes like copper, zinc, aluminium, chlorine, mercury, platinum etc. Elements for making electrodes are selected on the basis on their relative tendencies to gain and loose electrons.
Platinum electrodes
They are electrodes surgically-implanted into the brain
Electrodes placed inside the cochlear receive the decoded signals. The 22 electrodes allow a range of different pitches to be detected. The electrodes stimulate the hearing receptors.
Approximately 16-20 electrodes
Approximately 16-20 electrodes
The calomel electrodes are usually used as the salt bridge.
it will be useless to use 3 electrodes. IT IS WASTE OF MONEY.Two , three or four electrodes can be used but it only increases the rate of reaction.
Electrodes... Positive (anode) and Negative (cathode) electrodes which are attached to the terminals. The electrodes provide the chemical energy which is converted to a flow of electrons. And the electrolyte, the electrolyte separates the electrodes but allows for the passages of electrons and ions for the electro-chemical reaction of the electrodes.
electrodes are used in all types of electric furnaces.
