Does alternating current turn on and off?

Electric current that flows continuously in a single direction is called a direct current, or DC. In alternating current, the electrons don’t move in only one direction. Instead, they hop from atom to atom in one direction for a while, and then turn around and hop from atom to atom in the opposite direction.

Which side of a battery does the electricity come out of?

positive
We say that electricity flows from the positive (+) terminal of a battery to the negative (-) terminal of the battery. We can imagine particles with positive electric charge flowing in this direction around the circuit, like the red dots in the diagram.

Is a car battery DC?

Car batteries feature both positive terminal (‘+’) and negative terminal (‘-‘), meaning that the batteries are Direct Current (DC) power sources – yes, it is that simple.

How can we reduce the amount of light given off?

Dirt on light fixtures reduces the amount of light given off. Light fixtures with open tops allow air currents to move dust up through the fixtures so dust and dirt do not accumulate on them. Add more light fixtures in appropriate places. Paint walls and ceilings light colours so light can be reflected.

What is an LC oscillator used for?

LC oscillators are extensively used in generating and receiving RF signals where a variable frequency is required. At low frequencies such as audio the values of L and C needed to produce a resonating circuit would be too large and bulky to be practical.

Is it possible to be done with lighting?

Overarching statements like being “done” with something as ubiquitous as can lighting is maybe a little dramatic, yes, but I’ve been discussing the topic with Emily back and forth for a few weeks now. It can be fun to be black-and-white about a topic to force people’s hand to make a decision.

Does walking under a streetlight turn it on or off?

Like most phenomena of this type, the evidence is almost exclusively anecdotal. Typically, a person who has this effect on streetlights — known as a SLIder — finds that the light switches on or off when he or she walks or drives beneath it.
