Unformatted text preview: can use a pair of needle ­nosed pliers to make neat, precise bends, a pair of diagonal cutters to snip the leads and wires to length, and a wire stripper to remove the insulation from the newly cut wire ends. Neatness can improve your clarity of understanding of the circuit. However, you will be graded on the function of your circuits, not their appearance. Your breadboard has rows of connected holes that run the length of the breadboard, often with red and blue stripes marking them. They are usually used for the positive and negative terminals of the battery or other power supply voltage. Other components are inserted in the shorter 5 ­hole rows that run across the board. Figure P2 ­5 shows a typical component layout for a voltage divider. Important! Disconnect the battery when you are not using the circuit (taking measurements). This is good advice for all of the labs. If you leave the battery connected when you are not using the circuit, the battery will discharge and you will have to buy another one. Procedure 3 (20 points) Voltage Divider Objectives • In this procedure, you will build a voltage divider and compare the measured voltage to the ideal computed value. Measurements and Questions: 3. a (3 points) • Draw a circuit diagram for a voltage divider using a 9 V battery, a 10 kΩ resistor, and a 30 kΩ resistor. For the benefit of the grader, connect one end of the 30 kΩ resistor to the negative battery terminal. 3. b (4 points) • • Compute the value of the voltage across the 30 kΩ resistor in the circuit of part a using nominal component values (9 V, 10 kΩ, 30 kΩ). Also compute the range o...
