When circuit boards used in the manufacture of compact disk players are tested the long run percentage of defectives is 5%. Consider a random sample of 25 circuit boards. Let X be the number of ANR Building, Davis. Staff Meeting. February, 2015. Electrical Hazards/Injuries. Electrical equipment used in office areas is potentially hazardous . and can cause:. Shock. – most common hazard, occurs when the human body becomes part of the path through which the current flows. Electrical circuits require protection to prevent fire or electrocution in the event of a fault. There are two main types of circuit protection used RCD’s and MCB’s. . (RCD) Residual Current Device.

RELAY. 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.. Making Electricity Useful. Circuit Diagrams. Electrical circuits can be shown in diagrams using symbols:. 9.0V.

Energy GAINED by electrons:. The electrons in a wire gain potential energy when passing through the cell or battery.. Electromotive force (emf) . 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. . 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/.
