Electrical Safety in the Perioperative Environment There are numerous ways electricity is employed in the operating room environment‚ such as X-ray machines‚ electrosurgical units‚ monitors‚ surgical table and lights‚ endoscopic cameras and monitors‚ lasers‚ and robotics. Each piece of machinery comes with certain safety precautions when using them in the perioperative environment. Since almost all injuries in the OR result in human error‚ it is important to follow these precautions to ensure

there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area because the Agar cubes with a larger total

Electrolytic Conduction Introduction Electrical conductors can be classified into two types: (1) electronic conductors and (2) electrolytic conductors. Solid and molten metals‚ semiconductors‚ and some salts are examples of electronic conductors. Conduction takes place in electronic conductors by direct migration of electrons through the conductor under the influence of an applied potential. Here the atoms or ions that compose the conductor remain stationary (except for vibrations about

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top

Jones Electrical Distribution Case Case II Jones Electrical Distribution is a small company involved in wholesales of electrical devices and appliances. Even though Jones Electrical has been able to turn a profit over the past few years‚ they have noticed a shortage of cash when attempting to take advantage of trade discounts. Their current bank is unable to extend financing over $250‚000‚ and Jones believes they will need considerably more to finance their operations. Therefore‚ Nelson Jones

Application 1. What are the laws of series resistors? Of parallel resistors? Are these laws verified in your experiment? Ohm’s Law - Ohm’s law states that the voltage (V) across a resistor is proportional to the current (I)‚ where the constant of proportionality is the resistance (R). Series and parallel resistors - The total resistance of resistors connected in series is the sum of their individual resistance values. The total resistance of resistors connected in parallel is the reciprocal

or try repairing any electrical equipment or circuits with wet hands. It increases the conductivity of electric current. 2. Never use equipment with frayed cords‚ damaged insulation or broken plugs. 3. If you are working on any receptacle at your home then always turn off the mains. It is also a good idea to put up a sign on the service panel so that nobody turns the main switch ON by accident. 4. Electrical hazards include exposed energized parts and unguarded electrical equipment which may become
