2.2k 2.2k 2.2k DC 2.2k UNIVERSITY OF CALIFORNIA, BERKELEY EE 4 0 Summer 2008 Lab 2 Equivalent Circuits Guide Important Notes Please make sure the current limit set higher than the current required by the circuit but lower than 2 amps. This is to ensure that you provide your circuit with enough power without damaging the equipment. Always use measuring devices (DMM) to take your measurements. Do not depend on the power supply to report accurate voltage and current values. In this lab, you will use 1.2k , 2.2k , 220 , and 1k resistors. For this lab, you can use resistor values are at within 10% of your theoretical value. If you require the use of other valued resistors, then your theoretical calculations are incorrect. These circuits are complicated. Good breadboard practice will be key in completing this lab. Equivalent Resistor Networks Figure 1 1. Build the circuit shown in Figure 1. To demonstrate the importance of a neat and orderly breadboard layout, use only the resistors and no extra wires (except those connecting o the power supply) to build this circuit. Assuming a maximum of 10 volts, what is the maximum amount of current supplied by the power supply? 2. From your prelab, you calculated the theoretical resistance across
