The two most common materials used to make anodes are graphite and metals such as zinc, aluminum, or magnesium. Graphite anodes are often used in applications where high levels of electrical conductivity and chemical resistance are required, while metal anodes are typically used in sacrificial anode systems to protect steel structures from corrosion.

What happens to the mass of the metal anode as the cell continues to operate?
As the cell operates, the metal anode loses mass due to oxidation as it gives away electrons. This process results in the anode material dissolving into the electrolyte solution.
In the production of anode rays why perforated cathode plate is used?
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
Which anode in electrolysis?
The anode in electrolysis is the positive electrode where oxidation occurs. This means that electrons are released from the anode, causing ions to be attracted towards the cathode for reduction.
What is the direction electron flow during the x ray exposure?
During X-ray exposure, electrons flow from the cathode to the anode in the X-ray tube. This flow of electrons generates X-rays by interacting with the anode target material, producing high-energy photons that are used for imaging purposes.
Can an anode be dug up and moved?
Yes, an anode can be dug up and moved if necessary. Anodes are sacrificial components used to protect metal structures from corrosion, so if the anode is not effectively protecting the structure in its current location, it can be relocated to improve its effectiveness.
Is anode the electron-providing electrode?
Yes, anode the electron provides electrode. It is stated that an electrode is a conductor that is used to make contact with non-metallic parts of a circuit.
What is a sacrificial anode and how does it protect galvanized pipe?
A sacrificial anode is used to send stary current to ground through the anode. This wiil cause the anode to be eaten away saving the pipe from this effect. If you put two dissimilar metels together like brass and iron, it can make a weak battery and make a current. Some soils or other environments can cause this effect.
What is the gas liberated at anode in the manufacture of caustic soda using nelson cell?
The raw material for the manufacturing of caustic soda is sodium chloride so gas liberated at anode is chlorine.
Can you call forward bias voltage as positive voltage?
it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased .it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biasedit the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biasedex.anode - 5v cathode - 3vanode - 1v cathode - -2vboth the examples are forward biased.
What material is used to make art?

How is the metal used in an anode different from the metal used in cathode?
copper-zinc
What material was used to make flour sacks?
Cotton was used to make flour sacks.
What material did people in the Stone Age use to make a needle?
The most commonly used material to make needles was antler, sometimes bone was used.
What material is used to make film?
Cellulose
Which material is used to make sand?
Rocks.
What material is used to make the saxophone?
brass
What is a Programmable unijunction transistor?
PUT: programmable unijunction transistor It is a device like the thyristor only the gate is connected to the N type material near the anode. It is usually used in time delay, logic and SCR trigger circuits In the PUT, Gate is always positively biased w.r.t cathode. When anode voltage exceeds the gate voltage by about 0.7 V, first junction that is the junction right after the anode gets forward biased and PUT turns on. When anode voltage becomes less than the gate voltage, PUT is turned off.
