Resistance of wire of different sizes and length, sizing wire for a given load. Instantaneous values, maximum values and phase angles of an AC sine wave. Prerequisites: EFS 106, or Instructor's permission.

 
Learning Outcomes:

• Upon the completion of chapter eleven and at the end of chapter test, the student will be able to solve for percentages, evaluate conversion factors for electrical and mechanical power, find efficiency of electronic components, determine input and output of electrical devices, load matching and power transfer.
• Upon the completion of chapter twelve and end of chapter test, the student will demonstrate the ability to solve ratios and proportions, learn the American Wire Gage Table (AWG), resistance of wire of different materials, resistance of wire of different lengths, resistance of wire of different cross sectional area, and resistance of wire of any diameter, any length, or any material.
• Upon the completion of chapter thirteen and end of chapter test, the student will demonstrate the ability to determine the maximum current carrying capacity of wires, find the maximum size of wire to a given load. Calculate the correct size of wire to prevent excessive voltage drop.
