Define the IEC definition of `Low Voltage'. <br />2. Explain what frequency of an AC sine wave is. <br />3. List the two most common frequencies used in AC power transmission. <br />4. Explain what property of electricity affects the size of electrical conductors. <br />5. Explain what a Bridge Rectifier is, the schematic symbol, and what function a Bridge Rectifier <br />serves. <br />6. Explain the difference between Neutral and Ground. <br />7. Explain basic steps of troubleshooting. <br />8. Explain the properties of voltage, current and resistance and how they interact with each other. <br />9. Explain Watt's Law and the three formulas associated with it, and use the formulas to make <br />calculations for power, voltage, and current, <br />10. Explain Ohm's Law and the three formulas associated with it, and use the formulas to make <br />calculations for voltage, current, and resistance, <br />11. Explain the relationship between voltage, current and resistance in series and parallel <br />arrangements. <br />12. Explain the two most relevant Principles of Electromagnetism: <br />o Current flow through a conductor produces a magnetic field. <br />o Relative motion between a conductor and a magnetic field will induce current in the <br />conductor. <br />13, List various electrical components that utilize electromagnetic Induction to operate. <br />14, Explain the purpose of transformers and how they work. <br />15.
