Every inch of the way from the electric power generator to the outlet in your house. At times, the generator that produced the power for your house may be located in another state, several hundred miles away.
With electricity from the mains, the current chages direction 50 times each second, so it is called alternating current.
Direct current has no frequency, it has voltage. also it has current that is measured in Amperes which is dependable of the resistance of the circuit. Alternating current has frequency because the electricity flows alternatively on both directions. If the frequency of AC is 50hz/s it means that the electricity flows forwards and backwards 50 times per second.
2 times per second x (2.5)= 5 volts 6 times per second x (2.5)=15 volts
'Hertz' is the modern name for 'cycles per second' and represents how many times an alternating current (AC) changes from + to - per second and has nothing to do with voltage that can be either AC or DC. Tus if you have an alternator and can rotate the shaft 60 times per second with a voltage of 120 volts you will produce the same AC voltage that you find in your wall outlet (Alternators produce AC while generators produce DC electricity.
Light travels approximately 186,282 miles per second. So, in 20 seconds, light would travel around 3,725,640 miles.
how many times could you travel the world in 6000,000 miles.
Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second). That means light can travel around the Earth about 7.5 times in one second! It's the fastest thing in the universe that we know of.
Light cannot travel around the Earth, since light travels at a straight line and the Earth is round. The speed of light is 300,000 kilometers per second.
300,000 kilometres per second, or 186,000 Miles per Second, or 11,160,000 Miles per minute, or 669,600,000 Miles per Hour (Thats six hundred and sixty nine million, six hundred thousand miles per hour) It's also like 7 times around the world in a second!
In vacuum, the speed of light is -- 299,792,458 meters per second -- 186,282.397 miles per second. If you were to travel at the speed of light, you could go around the Earth's equator approximately 7.6 times in one second. (Flying in a typical passenger jet, at a ground speed of 500 mph, it would take 4 hours to cross the continental US.)
65mph times 3hours = 195 miles traveled
Less than the blink of an eye; about 0.0107 second.
Because light travels approximately 87,319 times faster than sound. Light speed is 186,282 Miles Per Second Sound travels at 768 Miles Per Hour (for conversion that is 768 divided by 360 to get Miles Per Second for comparison and calculation).
1200 divided by h times s
Light travels at 300,000 km/sec. (in a vacuum). That is enough to go 7 1/2 times around the Earth in a second (but note that light has a natural tendency to go in a straight line).
There is 86 400 seconds in a day so just times that by 8 which equals 691 200
