The DNA fragment size decreases as it moves from the cathode to the anode. This is due to the negative charge of the DNA moving against the positive charge of the cathode.

Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?

The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!


What happens at the anode of an electrolytic cell?

Oxidation occurs at the anode of an electrolytic cell.


Why electron move from anode to cathode in microbial fuel cell?

Electrons flow from the anode to the cathode in a microbial fuel cell as a result of the electrochemical reactions occurring at the electrodes. During the oxidation of organic matter at the anode, electrons are released and travel through an external circuit to the cathode, where reduction reactions occur. This electron flow generates a current that can be harnessed for electricity production.


Which electrode do the copper iron move towards?

Copper ions will move towards the cathode (negative electrode) and iron ions will move towards the anode (positive electrode) in an electrolytic cell.


How does a fuel cell convert chemical energy to electrical energy?

A fuel cell converts chemical energy to electrical energy through an electrochemical reaction. The fuel cell consists of an anode (negative terminal) and a cathode (positive terminal) separated by an electrolyte. Fuel (such as hydrogen) is fed to the anode and oxygen is fed to the cathode. At the anode, hydrogen is split into protons and electrons. The protons move through the electrolyte to the cathode, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons and electrons combine with oxygen to form water, releasing energy in the process.

What is the ion release in between cathode and anode?

Ions are released at the anode during oxidation, and they move towards the cathode through the electrolyte. At the cathode, the ions gain electrons and are reduced. This process results in the transfer of ions between the cathode and anode.


In electrolysis electrons move between two metal strips called?

Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.

What happens to voltage as you move the anode and cathode closer in a fruit battery?

the voltage will go down when the anode and cathode are closer together but will go up when they are further apart


What is fixed base biasing?

baiasing mins electronic move from anode to cathode


In the electrolytic cell electron flows from?

In the electrolytic cell, electrons flow from the negative terminal (cathode) to the positive terminal (anode). This flow allows for the oxidation of ions at the anode and the reduction of ions at the cathode, resulting in the desired chemical reactions to occur.

How is the metal used in an anode different from the metal used in a cathode?

Anode is positive and cathode is negative. Cathode is the longest led frame. Anode is where the oxidation reaction takes place while cathode is where the reduction reaction takes place or in a galvanic corrosion the anode is the metal that corrodes while the cathode is protected.


What is the opposite to a cathode?

A cathode is an electrode through which electrical current exits a polarized electrical device. Its opposite is the anode, through which electrical current enters the electrical device. Positively charged ions, called cations, move towards the cathode, while negatively charged ions, called anions, move towards the anode.


How a battery cause electron in move in a circuit?

It is an oxidation/reduction reaction. Electrons flow from anode to cathode.


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 happens at the anode of an electrolytic cell?

Oxidation occurs at the anode of an electrolytic cell.
