Equipments used in this experiment are (see Figure 1): Resistor board, power supply, digital multimeter, ammeter, several test leads. When using the digital multimeter to measure the resistance or voltage , connect the V/Ohm and Com to the connectors on the resistors (see Figure 3). Set the multimeter (or voltmeter) on the 20 DCV range to measure the voltage (see Figure 3). Figure 4 shows an example of the connected circuit.

• Perform the experiment ahead of time!
• Make sure the students have let you check the circuit before they turn on the power supply.
• Remind the students that in part II, don't let the voltage exceed 15 volts and in part III, don't let the current exceed 30mA.
• Before turning on the power supply, set its output to zero and increase it gradually after applying power.
