Electrons flow from the cathode, which has a high concentration of electrons to which electrode?

Electrons flow from the cathode to the anode due to the difference in electric potential. The cathode is the negative electrode, where there is a higher concentration of electrons, while the anode is the positive electrode that attracts electrons. This movement of electrons is fundamental to the operation of electrical circuits, as electrons are driven from areas of higher negative charge (cathode) to areas of lower negative charge (anode).

The concept of cathodes and anodes is crucial in understanding electrochemical cells and electronic devices, where the flow of electrons is essential for generating electric current. The anode is where oxidation occurs, and as electrons leave the cathode, they enter the anode, completing the circuit.

Other options, such as the negative plate and ground electrode, do not accurately represent the behavior of electron flow in relation to an anode. The negative plate does not serve as a destination for electrons in this context, and while a ground electrode can be part of a circuit, it is not the primary location to which electrons flow directly from a cathode.
