The film explains the measurement of electric current using ammeters, which quantify the flow of elementary charges in a circuit. It introduces the concept of amperes as a measure of the number of ...

Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing. Physicists have discovered one way to ...

The film explains the concept of electrons and their role in electric circuits. It describes how electric current is the flow of electric charges, primarily electrons, which cannot be seen but can be ...

In physical systems, transport takes many forms, such as electric current through a wire, heat through metal, or even water through a pipe. Each of these flows can be described by how easily the ...

In school, you might have learned that electrons were negatively charged and protons were positive. This is not a fact of nature but a human-invented convention. It’s a fact that protons and electrons ...
