Unformatted text preview: #______NAME______________________________________PERIOD______DATE________________ AP Physics B – Electric Circuits – HW 8-4 1. Which two arrangements of resistors shown above have the same resistance between the terminals? 2. In the circuit shown above, what is the value of the potential difference between points X and Y if the 6-volt battery has no internal resistance? 3. A lamp, a voltmeter V, an ammeter A, and a battery with zero internal resistance are connected as shown above. Describe how connecting another lamp in parallel with the first lamp as shown by the dashed lines would affect the readings on the ammeter and voltmeter. Questions 4-5 relate to the five incomplete circuits below composed of resistors R, all of equal resistance, and capacitors C, all of equal capacitance. A battery that can be used to complete any of the circuits is available. 4. Into which circuit should the battery be connected to obtain the greatest steady power dissipation?...
