Electricity moves fast—so fast that when you flip a light switch, the bulb seems to glow instantly. But how fast is it really? The answer depends on what part of electricity we’re talking about. • The movement of individual electrons in a wire, called drift velocity, is actually quite slow. Electrons bump into each other and take a long time to travel through a circuit. However, the signal that pushes them forward—like a chain reaction of dominos—moves at nearly the speed of light! This is why electrical energy reaches your devices almost instantly, even though the electrons themselves are moving sluggishly. • Electricity’s speed can change depending on the material it travels through. Copper wires, used in most electrical wiring, allow fast movement because they have low resistance. Fiber optic cables, used in modern internet connections, send signals even faster by using light instead of electrons. • Whether powering your phone, running through power lines, or lighting up entire cities, electricity is one of the fastest forces we rely on every day. While electrons may take their time, the electrical energy they carry zips through circuits at mind-blowing speeds, keeping our world connected in the blink of an eye! • • More Lessons: http://www.MathAndScience.com • Twitter: / jasongibsonmath
