There is no voltage drop across its terminals. The Diode Experiment 9. If you have access to electronic equipment, you may wish to perform the simple experiment described in the next few problems. If this is the first time you have tried such an experiment, get help from an instructor or someone who is familiar with electronic experiments. If you do not have access to equipment, do not skip this exercise. Read through the experiment and try to picture or imagine the results. This is sometimes called “dry-labbing” the experiment.

11. The circled A and V designate meters. The ammeter will measure current, and the voltmeter will measure voltage in the circuit. 11 You can use two multimeters set to either measure current or voltage. Because you need to change the resistance at each step in the experiment, try using a 1 megohm potentiometer and measure its resistance value after each adjustment. If you don't have a 1 megohm potentiometer, but do have a collection of resistors with values ranging from a few hundred ohms to 1 megohm, you can simply change resistors at each step.

As discussed later, this assumption is often used in many electronic designs. Questions A. 16. 16 VD = _____ V = Vs − VD = _____ ID = _____ B. 16. VD = _____ VR = Vs − VD = _____ ID = _____ Answers A. 3 mA B. 0 V; 10 V; 10 mA; 10 mA 16. The difference in the values of the two currents found in problem 15 is less than 10 percent of the total current. 7 mA is less than 10 percent of 10 mA. Many electronic components have a plus or minus 5 percent tolerance in their nominal values. This means that a 1 k resistor can be anywhere from 950 ohms to 1,050 ohms, meaning that the value of current through a resistor can vary plus or minus 5 percent.
