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.
Is Standard Calomel Electrode can act as cathode?
Yes, the Standard Calomel Electrode (SCE) can act as a cathode in certain electrochemical cells. When connected to a suitable anode in a galvanic cell or connected to a positive terminal in an electrolytic cell, the SCE can gain electrons and undergo reduction at its surface.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
What do you call a negative electrode?
Cathode- is the negative electrode.Anode- is the positive electrode.
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 the negative electrode of a voltaic cell called?
This is the anode.
What is an electrobe that has a positive charge?
Assuming this is a misspelling of "electrode" ... Electrochemistry can be confusing, because the answer depends on the type of device! In a galvanic cell (or discharging battery), the positively charged electrode is the cathode. However, in an electrolytic cell (or recharging battery), the positively charged electrode is the anode. The easiest way to keep this straight is to remember that the cathode is the one the cations (positively charged ions) migrate towards, and the anode is the one the anions (negatively charged ions) migrate towards.
When the switch is closed which electrode will attract the sodium ion?
Negative electrode Cathode One on the right
Which electrode of a voltaic cell the cathode or the anode corresponds to the higher potential energy for the electrons?
Cathode
