READING Comprehension Read the text below, then turn to the following page and choose the best answer for each item. Electricity is a fascinating part of our modern world. Walk into a room, flip a switch, and the entire room is lit up. Almost every room in the modern American home has something that is charged with electricity. From computers, phones, and televisions to vacuums, blenders, toasters, and more — all need electricity to function. So how do all of these electronics receive their power? Through the transfer of electrons. Any electrical device in your home is going to run off of an electrical circuit. This circuit is like a channel, made of wire that electrons can float through. When you attach these wires to a power source, like a battery, it gives the electrons voltage, so they can move. When the electrons move through the wire and reach an electrical device, it powers up and is ready to work. An important note about electrical circuits is the way in which they function. The word circuit is similar to the the word "circle." This is helpful to remember because this is how circuits work. The wire must run from the electrical power source to the device, and then back to the power source, creating a circle. This allows the electrons to travel to the device and back from it. Most electronics have an on/off switch to control the power flowing to the device. When the switch is off, it creates a break in the circle, which prevents the electrons from circulating back and forth. When the switch is turned on, it completes the circuit (closing the break), allowing the electrons to flow back and forth from the power source. Page 3 Copyright © 2018 by Academic Excellence, Inc.
