Let's analyze the following circuit. There are three DC batteries: three resistors. two switches (51.. 53}. six labeled points (P1: etc}: and a ground connection. Both switches are suddenly closed. R P 7 Upper V , S] '0 Middle 7. Considering your answers to the previous two questions, is it possible for the current to flow from right to left through R, and to flow from left to right through R,? Explain why or why not. 8. Now predict the correct current directions and explain any remaining logical steps. Mark those current directions on the original diagram. Use , for the current in the upper branch, etc. 9. Write Kirchhoff's junction rule at P1- 10. Which current flows through $1? Explain your reasoning
