Abstract The main objectives of this lab are to introduce 4-band color code resistors, familiarize students with basic measurements of resistance, voltage, and current. Also students will be introduced to the rules for resistance, voltage, and current in a series and parallel. Solenoids will also be used in this lab; solenoids are an electromechanical switch, used to control the flow of a liquid. Using this fluid, we are able to change electromechanical energy into linear movement. When the right switching voltage is used, the solenoid will change the directed flow of the fluid inside the cylinder. In this lab, we have pneumatic cylinders; however, solenoids are also capable of controlling hydraulic cylinders. In this lab students will measure voltage, current, and resistance with a multi-meter I

Introduction The main purpose of this lab is become familiar with measuring resistance, current, and voltage, along with the use of solenoids. Solenoids are an electromechanical switch, used to control the flow of a liquid. Using this fluid, we are able to change electromechanical energy into linear movement. When the right switching voltage is used, the solenoid will change the directed flow of the fluid inside the cylinder. In this lab solenoids are also able to control hydraulic cylinders. Procedure The materials needed for this lab are as follows: A solenoid Relays Wire The DAQ board Experiments: Experiment 1: Reading and measuring resistance Choose three different resistors from the lab kit. For each, record the color code of the resistor. Work out the resistance using this code and the color code listed on the card provided in the lab kit. Then set the digital multi-meter (DMM) to ohms. Place the leads of the DMM on each side of the resistor, and record the value displayed. You may need to vary the magnitude setting on the
