G Presentation Sessi. 5 JoHeCo] EOS Actio. S zoom links E Reading li. >> The students are tasked with building a simple Wimshurst machine. After studying different materials to be used for different parts of the machine, they list their conclusions as shown. Circle the letters of all the student conclusions that describe which materials could be used to build different parts of the simple Wimshurst machine. Wood is a good material for building parts of the machine that A should be insulated. Plastic is a good material for building the Leyden jars because plastic easily holds a static electric charge. Rubber is a good material for building the disks because rubber has many free electrons moving through it. Copper is a good material for building the brushes because D copper has many free electrons moving through it. Aluminum is a good material for building the handle because E aluminum is a conductor, and eléctric charge easily moves through it. O us VI 8:06 hp

20 What is countertorque a measure of? PRACTICAL APPLICATIONS ou are working as an electrician in a large steel manufacturing plant, and Y in the of doing preventive maintenance on a large DC you are generator. You have megged both the series and shunt field windings and found that each has over 10 M2 to ground. Your ohmmeter, however, indicates a resistance of 1.5 2 across terminals S, and S,. The ohmmeter indicates a resistance of 225 N between terminals F, and F2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer. process

12. You plot the current-voltage characteristics of a new non-ohmic device, perform a curve fit, and discover the current as a function of voltage is given by the equation: I = (9Amp/volt")V² – (7Amp/volt) V (a). Perform calculations to find the slope of a line tangent to this curve when V = 4.15 volts. (b). Calculate the effective resistance of this device when V = 4.15 volts. This device is Non-Ohmic!
