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 happens when smaller area is provided to cathode than anode?
When the area provided to the cathode is smaller than the anode the electrons will still flow.
How many terminals does a diode have?
two, cathode & anode
Will electrons flow from anode to cathod?
"from anode to cathode". Normally, no. Taking a radio valve (electron tube), since the anode is positive compared to the cathode, and since electrons flow from surplus (at the negative cathode) to deficiency (at the positive anode), they do *not* flow from anode to cathode in normal operation. It's possible to have electrons striking the anode and *knocking off* electrons from it, and then to have those electrons travelling back towards the cathode. This is secondary emission. It was a problem in four-element "tetrode" valves in the early days, but has now been eliminated in practical designs. Long story short: it's possible, but undesirable and not common.
How is the formation of anode and cathode rays?
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electronswhich move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode
What is cathode and anode?
cathode is electron negative but anode is positiveAnswerFor electrochemical cells, electrons travel through the external circuit from the anode to the cathode.
The relationship between a cathode and an anode involves what?
The relationship between a cathode and an anode involves
On a silicon-controlled rectifier which wire is the anode and which the cathode?
Anode is positive, cathode is negative
That is function anode and cathode piping?
that is function of anode and cathode in underground piping yes
What is the anode and cathode of Baghdad's battery?
the copper cylinder(cathode) and iron rod(anode)
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
The terminals of a diode are called the?
anode positive potential cathode negative potential
What is the difference between anode and cathode in a battery?
In a battery, the anode is where the electric current flows in, while the cathode is where the current flows out. The anode is negatively charged, and the cathode is positively charged. This flow of electrons between the anode and cathode creates the electrical energy in a battery.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
In a simple cell the cathode or the anode is more reactive?
In a simple cell, the anode is typically more reactive than the cathode. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting those electrons. This difference in reactivity drives the flow of electrons from the anode to the cathode, generating electrical energy.
What is the difference between a cathode and an anode in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode, while the anode is the positively charged electrode. The flow of electrons is from the anode to the cathode.
