Anode : The end which is at a lower negative potential
Cathode: The end which is at a higher negative potential
AnswerThe cathode is the terminal towards which free electrons drift in a cell's external circuit.In other words, when the cell is discharging, it is the positive electrode.

How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
When you are forward-bias testing with a digital vom the red test lead should be placed on which lead of the diode?
The anode (the cathode is usually marked with a stripe).
What sort of diode do you need when putting a solar cell on a battery powered device?
There are two basic types of diodes; Silicon and Germanium. I would use germanium because it has a lower forward bias than silicon. I suspect that what you really want to know is how to hook up an isolation diode. This is a diode that is installed in series with the alternate power source to isolate one from the other. Whether you use germanium or silicon the way that you want to hook it up is pretty straight-forward. go ahead and hook the negative (black) lead of the solar cell to the negative (black) lead of the battery. Hook up the positive (red) lead of the solar cell to the anode of the isolation diode and the cathode end of the diode hooks up to the positive (red) lead of the battery. You can identify the anode and cathode ends of the diode by looking on the diode - you will see a little diagram that looks like an arrow with a straight line at the tip of the arrow. the straight line side is the cathode end. Unless you have a really big solar panel you could probably use a general purpose diode such as a 1N4001 silicon (available at radio-shack)Hope this helped you.
What is mean't by Reverse voltage?
Reverse voltage is voltage is applied in reverse. Instead of the positive voltage going into the anode lead of a component, it goes into the cathode lead of the component.
Is the short lead the cathode on an led?
Yes
What metal is present at both cathode and the anode in a car battery?
Lead
Name of positive and negative plates of a lead battery?
Anode and cathode
0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
What are two terminals in a battery?
In a car battery, the terminals are the heavy lead posts sticking up from the top of the battery, one labeled positive and one negative. Car batteries are of the lead-acid design, in which the anode (positive side) and cathode (negative side) are made of lead and lead dioxide, and as current leaves the battery through the anode both electrodes (anode and cathode) are chemically converted to lead sulphate. Cars use an alternator to send some of the current from the battery back to the anode, which partially converts the lead sulphate back into lead and lead dioxide, thus greatly lengthening the life of the battery.
What is the name of the battery positive and negative plates in a typical lead acid battery when the battery is in a charged condition?
anode (negative) cathode (positive) Source: www.bdbatteries.com
What is the electrolyte in a storage battery?
Electrolyte acts as a good conductor in liquid state. It makes the cations and anions to move towards cathode and anode respectively thus conductiog current.
What are the products of the electrolysis of lead nitrate solution?
Pure lead on the cathode and oxygen at the anode.
The lead-acid consist of primarily two electrodes namely?
The Anode and the Cathode.
What are the products of the electrolysis of aqueous lead nitrate?
Oxygen on the anode and lead on the cathode. Since it's electrolysis, the reaction is not spontaneous.
What are the three main components of a battery?
Batteries are made up of zinc, zinc chloride and ammonium chloride. There is also a basic element called an electrochemical cell in the batter also.Batteries have three sections, an anode (- ), a cathode (+), and the electrolyte. The cathode and anode are connected to an electrical circuit. The chemical reactions in the battery cause a development of electrons at the anode.
What is the cathode in an electrochemical cell?
The electrode at which a reduction reaction occurs.PhysicsA cathode is the element of an electron tube from which electrons flow. Back in the day, current was thought to be positive, but we understand things differently now. In the "old school" version, the cathode was the element into which positive charges flowed. But that's usually not what is taught for the simple reason that it's a classical physics approach and isn't at all as useful as the idea that the cathode is the element from which electrons leave to go to the plate.In a two-element tube, the cathode has a compliment called the anode, or plate. Electrons flow from the cathode to the anode. Not the other way. There are tubes with three, four, and more elements, but they have these two basic elements.ChemistryThe cathode is the electrode of a polarized electrical device, such as a galvanic cell, out of which positive electric current flows. In a battery like the one in a vehicle, the positive terminal is the cathode. The car battery, which is a lead-acid battery, also has an electrode that is the compliment to the cathode: the anode. It's the negative terminal of the battery, and positive electric current flows into this electrode.The Wikipedia article on the cathode covers both the chemistry application of the term as well as the physics application, and a link is provided.
How did the cathode's tube experiment lead to the conclusion that atoms contain electrons?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
