Learning Outcomes. Having completed this course the learner will be able to: - Describe the various terms associated with electrical drawings; - Identify the plans and drawings that are included in electrical drawings; - Discuss the uses of electrical. FIRST PRINCIPAL OF NATURAL SCIENCE X-RAY. X-ray imaging begins with a beam of high energy electrons crashing into a metal target and x-rays are produced. A filter near the x-ray source blocks these low energy rays, which means only the high energy rays pass through a patient toward a sheet of photographic film. Be well versed with electrical prefixes and have a basic understanding of voltage, current, resistance, and power as well as their units of measurement and abbreviations. Be able to calculate electrical power in watts and combine Ohm’s Law and Watt’s law to find unknown currents, voltages, resistance, and power. For example, a D battery is 1.5 joules (work) per coulomb (charge) or, more simply, 1.5 volts. Lesson Summary Electric potential is the level of power behind a flow of electricity, but shouldn't.
