How do electric currents create light?

Current and voltage combine as electric power to create light in several ways. Let's discuss just a few examples. In Nature, lighting is created by millions of volts accelerating electrons to heat up the atmosphere and that high temperature radiates light and even X-rays. read more

Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate. read more

Electric current is the rate at which electric charge flows past a point on the electric circuit. Water current is the rate at which water flows past a point on the water circuit. As such, current is analogous to the number of gallons of water flowing into, along, and out of a slide per unit of time. read more
