A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
When the area provided to the cathode is smaller than the anode the electrons will still flow.
two, cathode & anode
"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.
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
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
Anode is positive, cathode is negative
that is function of anode and cathode in underground piping yes
the copper cylinder(cathode) and iron rod(anode)
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
cathode rays can emit electrons anode can collect them
anode positive potential cathode negative potential
The Cathode is the negative electrode; the anode is the positive electrode
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.
Anode ray is positive and cathode ray is negative
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
