Question

Quizplus · Accepted Answer

In an ordinary electric circuit, the source of electrons is the electric conductor itself. Electrons are already present in the conductive material (like metals) and are made to flow through the circuit when a potential difference is applied. Other options like batteries, wall sockets, or generators are sources of electrical energy or potential difference, not the electrons themselves.
