What happens when electrodes touch in a battery?
BOOM
What must the electrodes of a cell have in order for it to produce a current?
The electrodes of a cell must be made of conductive materials to allow for the flow of electrons. One electrode must be a source of electrons (anode), while the other electrode must accept electrons (cathode) to complete the circuit and allow current to flow. Additionally, the electrodes must be immersed in an electrolyte that facilitates the movement of ions between the two electrodes.
What safety precautions should I take when installing batteries - like the kind that are in cars that have around 12V- and an electric motor to my go kart?
A voltage of 12 V - as used in car batteries - is not particularly dangerous. You can even touch the electrodes, though I suggest not to touch BOTH electrodes at once.
Why must two electrodes be used to make an electrical measurement such as pH?
Two electrodes are required to make an electrical measurement, such as pH, because a potential difference is created between the electrodes when they are in contact with the solution being measured. The potential difference is then used to calculate the pH of the solution based on the known properties of the electrodes and the solution.
What is evoked potential?
Evoked potential-- A test of nerve response that uses electrodes placed on the scalp to measure brain reaction to a stimulus such as a touch.
What is touch capture in chess?
Touch move means that if you touch a piece and it has a legal move you must play it. Touch capture means that if you touch a piece of your opponent's and you can capture it you must do so.
Is a stun gun and a tazer the same thing?
A "stun gun" is a general class of implements that generate a spark or electric discharge across two or more electrodes of opposite polarity by means of capacitor and are usually battery powered. The electrodes of a "stund gun" must come into contact with the skin of the recipient. A "TAZER" is a patented device that fires two electrodes by means of compressed gas. The electrodes are connected by wires to a main hand held unit which contains the batteries and capacitors and releases an electric shock through the opposite polar electrodes, which must imbed in the flesh/skin of the recipient to deliver the shock.
What are depth electrodes?
They are electrodes surgically-implanted into the brain
How does a spot welder work?
A spot welder uses 2 electrodes positioned opposite each other. 2 pieces of metal (usually thin) are placed like a sandwich between the electrodes which come together with force and an electrical current is passed thru them which actually melts the pieces where they touch each other. This produces a small weld "spot" . This spot is about the same size as the tips of the electrodes.
If two lines are coplanar then they must touch?
No. If they are parallel (but not identical), they will not touch.
What is Pt electrodes?
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
What the electrodes in the cochlear implant replace?
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.
