PPT-ES250: Electrical Science

Chapter 10 Sinusoidal SteadyState Analysis Linear circuits with sinusoidal inputs that are at steady state are called ac circuits eg the power system that provides us with electricity can be considered a very large ac circuit.

Volt. - Is the measurement unit of the electrical potential. . Electrical Potential. - The difference of voltage between two points in a circuit. It is the cause of the flow of a current. . Current- . What Are Electrical Risks. ?. Electrical risks are risks of death, electric shock or other injuries caused directly or indirectly by electricity. The most common electrical risks and subsequent causes of injury are. and Ohm’s Law. The basics of electrical measurement. . Voltage is electrical pressure, which is potential force or the difference in electrical charge between two points. Voltage pushes electrical currents though a wire but not through its insulation.. Electrical Awareness Statistics. Electrical . injuries account for 20,000 Emergency visits / year. Resulting in 1,000 deaths / year. Low-Voltage injuries (110-440V) account for 60% of all injuries. Understanding Electricity . Electrical Machines. 1. CHAPTER 1. ELECTROMECHANICAL ENERGY CONVERSION. Electrical Machines. 2. Introduction. Electro mechanical device converts energy between electrical and mechanical forms.. Electromechanical energy conversion theory helps in representing electromagnetic force or torque in terms of such parameters like electric current or displacement.. Up to this point we have learned that static electricity can build up to a point where it results in the discharge of that energy in the form of a spark or lightning strike.. Next we will draw on your prior knowledge (gr. 6) to help learn about currents and circuits. . INTRODUCTION. A motor is a machine which converts electrical energy into mechanical energy. A DC motor finds application in rolling mills, in traction system and overhead cranes. The principle of operation of DC motor is that when a current carrying conductor is kept in a magnetic field, a force is produced in that conductor. . Electricity - The Dangers. About 5 workers are electrocuted every week. Causes 12% of young worker workplace deaths . Takes very little electricity to cause harm . Significant risk of causing fires. What primarily causes electrocution?. Electrical Safety Statistics. On average, there are 70 electrocution fatalities due to consumer products each year. . http://www.cpsc.gov/en/Research--Statistics/Electrocutions1/Electrocutions/. Approximately half of home electrical fires involve electrical distribution or lighting.
