Which way do positive charges move?

Which way do positive charges move?

The positive sign for current corresponds to the direction a positive charge would move. In metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move.

Does light travel fast or slow?

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph.

What if the speed of light and sound were switched?

You can’t switch one with the other. The speed of light in a vacuum represents the speed at which events can happen. If say were switched with the speed of sound, sound could not move faster than light regardless. It will be talking in terms of speed of sound instead of vacuum speed of light.

What if you travel at the speed of light?

According to the video, if you’re traveling at nearly the speed of light, the clock inside your rocket would show it takes less time to travel to your destination as it would on Earth. But, since the clocks at home would be moving at a standard rate you’d return home to everyone else being quite a bit older.

What if we ran at the speed of light?

The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.

What if the speed of light was faster?

If the speed of light was, say, 100 km/h, we could experience the effects of special relativity in our day to day lives. Cars passing by would appear as pictures on a sheet of paper. Their headlights would be dark blue, perhaps even brightly violet, while their tail red lamps would be invisible.
