Unformatted text preview: R 1 ? (Hint: P R 1 = V R 1 I ). 5. What is the voltage drop V R 2 across R 2 ? (Apply Ohm’s Law between points b and c.) 6. What is the power used by R 2 ? 7. What is the voltage drop V R 3 across R 3 ? (Apply Ohm’s Law between points c and d.) 8. What is the power used by R 3 ? 9. Add the voltage drops across R 1 and R 2 and R 3 . V R 1 + V R 2 + V R 3 = 10. What is the total power drawn from the voltage source? 2...
