THE MECHANICAL UNIVERSE Video 33 – Electric Circuits Name: Class: 1. What famous royal figure attended a formal lecture given by Michael Faraday in the lat 1700’s at the Royal Institute? 2. The metropolitan water district supplies power to what major US city? 3. One Ampere is one Coulomb of charge flowing through a circuit in how many seconds? 4. Oerstead used the current flowing in a wire due to a voltaic pile to show the link between electricity and magnetism, today simply known as _________________________. 5. Wheatstone and Ohm showed that the telegraph signal could be sent over large distances if the ____________ was increased in proportion to _______________. 6. State Ohm’s Law in equation form and describe what it means in words. 7. Analogous to water pipes, the resistance of a resistor is….. R ________ ; R ____________ ; and R constant/__________ 8. If conductors are connected to a battery, an electric field is created inside a conductor, hence the valence electrons flow. What creates the “resistance”? 9. Applying the concept of conservation of charge, Kirchhoff developed the “junction rule”. It says “the current flowing into a junction __________ the current flowing _______ of the junction. 10. Kirchhoff other law states that as a charge flows around a complete circuit, it neither _________ or __________ energy. 11. Before a lecture in 1846, Charles Wheatstone became nervous and did what?
