In the circuit shown in the figure (Figure 1), the 6.0 ΩΩ resistor is consuming energy at a rate of 21 J/sJ/s when the current through it flows as shown. What are the polarity and emf of the battery EE, assuming it has negligible internal resistance? Express your answer with the appropriate units. Enter positive value if the polarity of the battery is the same as shown the figure and negative value in another case.
