Physics 4B Spring 2010 Answers: 1.(a) 0.706 Ω, (b) 11.2 V, 2.(a) 7.81 Ω, (b) 0.569 V, 3.(a) 1.52 ms, (b) 1/3E, 2/3 E, (c) 5/9 Conference # 8 – DC Circuits 1.(Ch. 28 Exercise 1) A battery has an emf Eand an internal resistance r. It is connected to an external resistor R. When R= 4 Ωthe terminal potential difference is 9.5 V, and when R= 6 Ωthe terminal potential difference is 10 V. Find Eand r. 2.(Ch. 28 Exercise 9) (a) Find the equivalent resistance of the combination of resistors shown in Fig. 28.36. (b) If a 10-V potential difference is applied across points aand bfind the potential difference across the 4-Ωresistor. 3.The resistance and capacitance for an RC series circuit are
