LAB 3 FIRST ORDER CIRCUITS Real Instruments Resistor, Capacitor and Inductors 1. INTRODUCTION First order systems or circuits in this case are called first-order because the system response is described by one first-order differential equation (typically one independent energy storage element). The RC circuit is governed by the following differential equation: u x x τ = + with τ = RC 2. OBJECTIVES s Test the step and frequency response of a resistor, capacitor and inductor. s Understand the basic characteristics of a high pass filter. 3. LIST OF COMPONENTS AND EQUIPMENT REQUIRED List of Components s Resistors: 200 Ω (1) s Capacitors: 0.1 μ F (1) s Inductors: 1 mH (1) s Hookup wire AWG # 22. Equipment required s Power Supply. s Signal generator. s Oscilloscope. s Digital Multimeter s Breadboard.

4. HANDS ON 4.1 STEP RESPONSE OF AN RL CIRCUIT Remember to set your Function Generator to “High Z” (you can find it under Utility>Output Setup) . Connect in series the 200 Ω resistor and the 1 mH inductor. Select a square wave with a frequency of 100 Hz, amplitude of 5 VPP and an offset of 2.5 volts. Figure 1 RL Circuit for Section 4.1 s Measure the inductor resistance using the Multimeter. s
