Basic Circuit Measurements and Ohm’s Law ECE 2100 Circuit Analysis Laboratory updated 8 September 2008 Pre-Laboratory Assignment 1. Read and study the ECE 2100 Laboratory: Safety and Rules document and the ECE 2100 Laboratory: Notebook Requirements document (available on-line). There will be a quiz on this material at the beginning of lab. 2. Read this laboratory. Procedures 1. Select six random resistors from the "grab bag" in front of the lab. Record the nominal, maximum and minimum resistance values of each resistor using the color band code. Using a digital multimeter (DMM), measure and record the resistance of each resistor. Complete the following table. number nominal maximum minimum measured 1 2 3 4 5 6 Notes: a. After measuring resistance, never leave a multimeter function switch in the OHMs position. Always return the multimeter to a voltage measurement mode or simply turn it off. b. Be sure to have your instructor review your results and initial your lab notebook before continuing. 2. Calculate the maximum allowable voltage (in Volts) and current (in mA) for a 1.0 kΩ, 1/4 W resistor. 1 3. Use a 1.0 kΩ, 1/4 W resistor, along with two DMMs, to construct the circuit shown below. Note that voltage is ACROSS the resistor and current is THROUGH the resistor. The ±48 V power supply on the bench panel should be used as the voltage source, being careful to initially turn it to 0.0 V and OFF. 4. Being careful to never exceed the maximum allowable voltage, measure and record at least 10 different voltage and current values as illustrated in the table below. Be sure to record the units associated with every measurement. VS (units) VL (units) I (units) 0 1.5 3 . . . 2
