Express your answer in teme ot I and V. Figure 1) The circuit in the diagram consists of a batery with EMF a resistor with resistance R n ammeter, and a voltmeter. The voltmeter and the armmeter labeled Vand A, respectively) cn be considered ideal, that is, their resitanoes are infinity and zero respectively. The current in the resistor is I, and the voltage across it s V. The interial resistance of the battery rint is not zero. Submit My Answers lve Up Part D Again, what is the power dissipated in the resistor? This time, express your answer in terms of one or more of the following variables: I, nt, and R Foure 1 of Submit My Answers Give Up & Fint Part E For the third time, what is the power P& dissipeted in the resistor? Express your anewer In tems of one or more of the following variables: E, int, and R. 8:41 PM Type: here to search ^" : 10/11/2011

Explanation / Answer

Part c) Power, Pr = V I

Part d) Power, Pr = I2 R

Part e) Power, Pr = 2R / (R + rint)2
