Unformatted text preview: f voltage using a 5% resistor value tolerance. 3. c (3 points) • Measure and record the actual battery voltage and resistor values. Using your multimeter. 3. d (3 points) • Compute the value of the voltage across the 30 kΩ resistor in the circuit of part a using the measured component values from part c. Note whether this number is within the range computed in part b. 3. e (3 points) •
• Build the circuit in part a using the components you measured, and measure the actual voltage across the 30 kΩ resistor. Discuss any differences with the result from part d. 3. f (4 points) • Describe in detail a specific example in current technology where a voltage divider is used. Procedure 4 (20 points) Current Divider Objectives • In this procedure, you will build a current divider and compare the measured voltage to the ideal computed value. (As an experiment, this is less satisfactory than the voltage divider because a battery is a voltage source, not a current source.) Measurements and Questions: 4. a (2 points) • Draw a circuit diagram for a current divider using a 9 V battery, a 1 kΩ resistor, and a 300 Ω resistor. For the benefit of the grader, draw the 300 Ω resistor on the right side of the circuit. 4. b (3 points) •
• Compute the value of the current through each resistor, and the total current leaving the battery, in the circuit of part a. using nominal component values (9 V, 1 kΩ, 300Ω). Also compute the range of total current using a 5% resistor value tolerance. 4. c (3 points) • Measure and record the actual battery voltage and resistor values. Using your multimeter. 4. d (3 points) • Compute the value of the c...
