In the circuit analyzed in Example 25.8 the 4.0- resistor

Chapter 25, Problem 25.48

(choose chapter or problem)

In the circuit analyzed in Example 25.8 the 4.0- resistor is replaced by a 8.0- resistor, as in Example 25.9. (a) Calculate the rate of conversion of chemical energy to electrical energy in the battery. How does your answer compare to the result calculated in Example 25.8? (b) Calculate the rate of electrical energy dissipation in the internal resistance of the battery. How does your answer compare to the result calculated in Example 25.8? (c) Use the results of parts (a) and (b) to calculate the net power output of the battery. How does your result compare to the electrical power dissipated in the 8.0- resistor as calculated for this circuit in Example 25.9?
