Question

Part A In the circuit shown in (Figure 1), the 6.0 $\Omega$ resistor is consuming energy at a rate of 22.0 J/s when the current through it flows as shown. Find the current through the ammeter A. Express your answer in amperes. Figure I = < 1 of 1 > Submit Previous Answers Request Answer Incorrect; Try Again; One attempt remaining Part B What are the polarity and emf $\mathcal{E}$ of the battery, assuming it has negligible internal resistance? Express your answer in volts. Enter positive value if the polarity of the battery is as shown in the figure in the problem and opposite to what is shown in the figure. $\mathcal{E}$ = -42 V Submit Previous Answers
