4. Today we use the terms "volt" and "voltage", but they are not the same thing. What is the difference in their meaning? How do we use each of these words now? 5. Musschenbroek's development of the Leyden Jar followed this process. He hoped to collect charge in the jar like a liquid, and store it for later use. In his initial experiments he did something that we now know caused his experiment to "fail'1 (i.e., no charge was stored in the jar); he placed the jar on an insulating disk of wax while attempting to charge it. What made that action consistent with his model? Or, in other words, what did his model predict would happen if he did NOT place the jar on an insulator, and why? 6. Why did news of the Leyden Jar have such tremendous impact around the world? 7. How did the Leyden Jar change people's mental model of electricity at that time? 8. Franklin and Volta profoundly changed the models of electricity shared by scientists in their times. by showing that the static electricity created by early electricians was the same as the electricity in Lightning (Franklin) and as that found in animals and even humans (Volta). How did the discovery of the electron change our understanding from the "Franklin Model" of electricity
