The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode.

What is meaning of perforated cathode?
The. Cathode plate consists of small holes known as perforated cathode plate
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
Why does the cathode gain in mass during the purification of copper by electrolysis?
Because the cathode is where reduction takes place, meaning the it gains electrons. When it gains electrons, it attracts the copper cation (Cu^2+) and as the copper cation reaches the cathode, it picks up the electrons from the cathode, and is deposited as solid copper (Cu). This results in the cathode gaining mass over time.
What is common cathode?
has common cathode
What is the difference between anode led and cathode led?
A: A LED is a diode and like all diode they have an [anode] meaning positive terminal and a [cathode] negative terminal. Therefore the proper potential must be applied for it to behave like an LED.
Where does reduction occur in an electrochemical cell?
The cathode.
Is the cathode positive in a battery?
No, the cathode is negative in a battery.
Is the cathode red or black?
The cathode is typically black.
Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
In the cathode ray tube where do the particles originate?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
What is the charge of the particle in cathode rays?
The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
