Mr. Phillips and his students are building a simple series circuit to learn about electricity. Which of the following will they need in order to demonstrate the flow of electricity through the circuit?
I. an energy source, such as a battery
II. wires than can conduct a current
III. a resistance, or receiver, such as a light bulb

A. II and III only
B. I and III only
C. I only
D. I, II, and III

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
