Waves and currents
When you hear the words waves and currents, your brain might immediately
make you think about the ocean, or at least some form of water. That’s natural,
since that is probably what you have experienced the most in connection to those
two words. But waves and currents can be talking about energy as well. Energy
travels in waves, and electric current is the constant flow of electric energy.
A wave, whether it is in the ocean, on land, or in the air, is simply the
movement that takes energy from one place to another. Many kinds of energy
travel in waves. Light, sound, and mechanical energy all travel in waves. Sound
waves, for example, are produced by the vibration of particles. Plucking a string on
a guitar or violin makes the air around the string move back and forth.
A wave can be measured based on a comparison of its highest point (crest)
and lowest point (trough). The distances between troughs and the distance
between crests are called wavelengths. You can use a timer to see how many crests
happen in a certain amount of time, and that will tell you the frequency of a wave.
The constant flow of charged particles is an electric current. Negatively
charged particles move toward positively charged particles. Electric current needs
an unbroken path, or circuit. A circuit is made of wires, an energy source and
something that requires energy. Then the current can flow!
