Physics in Action A string of 35 miniature decorative lights is wired in series. If it draws 0.20 A of current when it is connected to a 120.0 V emf source, what is the resistance of each miniature bulb?

A battery-powered global positioning system (GPS) receiver operating on a voltage of 9.0 V draws a current of 0.19 A Part A How much electrical energy does it consume during 50 minutes? Express your answer with the appropriate units. HA W = Value Units Submit Request Answer

How would the value of each of the four following physical quantities change over time after the switch is closed? Explain why for each case in 1 or 2 sentences. (You may assume that the resistance of the batteries, the wires, and the switch are negligibly small for this question). a. The voltage across the capacitor, VCAP b. The voltage across the light bulb, VBULB c. The current through light bulb, IBULB d. VBULB + VCAP

Real materials only have so many electrons (with fixed charge) that are free to move through a circuit. How can the same object allow different amounts of current to flow through it? Use what you noticed about the electrons in the simulation to justify your answer. image of simulation below
