Cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by an element. Cold cathodes are used in gas discharge lamps such as neon lamps and discharge tubes.

What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
What do you call a negative electrode?
Cathode- is the negative electrode.Anode- is the positive electrode.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
How would you identify the anode of unmarked diode?
If it's new, the cathode is the shorter lead.There may be a flat on the round base (on round ones) = cathodeThe larger electrode inside is the cathode.
Where did the electrons from cathode ray come from?
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.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
What is the alternative name for the negative electrode?
The alternative name for the negative electrode is the cathode.
What do you call a negative electrode?
Cathode- is the negative electrode.Anode- is the positive electrode.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
What electrode has a negative charge?
The cathode.
What is an electrode that has an netgative charge?
cathode
Where does reduction occur in an electrolytic cell?
The electrode where reduction occurs
What is Annode and Cathode in Chemistry?
In chemistry, the anode is the electrode where oxidation occurs during an electrochemical reaction, while the cathode is the electrode where reduction occurs. Electrons flow from the anode to the cathode. This process is essential in batteries, electrolysis, and other electrochemical systems.
Why is the beam of light called a cathode ray?
The beam of light is known as a cathode ray because historically it was produced in vacuum tubes by directing a stream of electrons from a negatively charged electrode (cathode) towards a positively charged electrode (anode), leading to the term "cathode ray." It was named so in reference to the electrode from which the electrons originated.
An electrode at which aluminium is deposited during electrolysis of alumina?
Cathode is the electrode at which aluminium is deposited during electrolysis of alumina. Aluminum ions (Al3+) are reduced to form solid aluminum metal at the cathode.
Which electrode of a voltaic cell the cathode or the anode corresponds to the higher potential energy for the electrons?
Cathode
