Unformatted text preview: I = V/R ) between points a and b in the equivalent circuit ): I T = 3. Calculate the current ( I 1 ) through R 1 (Apply Ohms Law between points c and d ). I 1 = 4. Calculate the current ( I 2 ) through R 2 (Apply Ohms Law between points e and f ). I 2 = 5. Calculate the current ( I 3 ) through R 3 (Apply Ohms Law between points g and h ). I 3 = 6. Add the currents: I 1 + I 2 + I 3 = How does this sum compare to the total currrent I T , leaving the battery? 3 7. What is the total power drawn from the voltage source? (Hint: Use P = V I Units of power are watts .) P T = 8. What is the power used by R 1 ? P 1 = 9. What is the power used by R 2 ? P 2 = 10. What is the power used by R 3 ? P 3 = 11. Add the powers used by the three resistors together: P 1 + P 2 + P 3 = How does this sum compare to the total power ( P T ) drawn from the power source? 4...
