Item 8 Learning Goal: To understand how to compute power dissipation in a resistive circuit. (Figure 1) The circuit in the diagram consists of a battery with EMF E, a resistor with resistance R, an ammeter, and a voltmeter. The voltmeter and the ammeter (labeled V and A, respectively) can be considered ideal, that is, their resistances are infinity and zero, respectively. The current in the resistor is I, and the voltage across it is V. The internal resistance of the battery rint is not zero. Figure Tint ww M <1 of 1 FailA What is the ammeter reading I?
