Voltage is the force that moves electrons through a circuit. The movement of electrons is called current. Computer circuits need voltage and current to operate electronic components. When the voltage in a computer is not accurate or steady, computer components may not operate correctly. Unsteady voltages are called power fluctuations. The following types of AC power fluctuations can cause data loss or hardware failure: Blackout - Complete loss of AC power. Brownout - Reduced voltage level of AC power that lasts for a period of time. Noise - Electrical interference from generators and lightning. Spike - Sudden increase in voltage that lasts for a very short period and exceeds 100% of the normal voltage on a line. Power surge - Dramatic increase in voltage above the normal flow of electrical current. To help shield against power fluctuation issues, use power protection devices to protect the data and computer equipment: A surge suppressor helps protect against damage from surges and spikes. A surge suppressor diverts extra electrical voltage on the line to the ground. Uninterruptible Power Supply (UPS) helps protect against potential electrical power problems by supplying electrical power to a computer or other device. Standby Power Supply (SPS) helps protect against potential electrical power problems by providing a backup battery to supply power when the incoming voltage drops below the normal level. CAUTION: Never plug a printer into a UPS device. UPS manufacturers suggest not plugging a printer into a UPS for fear of burning up the printer motor. Teaching Strategy: Dangers to computer equipment and data include; spike, power-in rush, brownout, blackout, lightning, jewelry, spills, and drops. Climate impacts probability of ESD. Devices that can protect the equipment from electrical damage include; Surge protector, UPS, antistatic mats and bags, antistatic wrist straps.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
