Excuse me: how to convert the unit of time? For example, 1 second =? Millisecond, 1 millisecond =? Microsecond

1 second = 1 000 millisecond (MS) 1 millisecond = 1 / 1000 second (s) 1 second = 1000000 microseconds (μ s) 1 microseconds = 1 / 1000000 seconds (s) 1 second = 1000000000 nanoseconds (NS) 1 nanoseconds = 1 / 1000000000 seconds (s) 1 second = 1000000000 picoseconds (PS) 1 picoseconds = 1 / 1000

What is the conversion relationship among seconds, milliseconds and microseconds?
Is there a 60 system between them, such as whether one second is equal to 60 milliseconds, and one millisecond is equal to 60 microseconds
Why does the stopwatch display 100 times full, that is, 100 times full is 1 second

No
It's the third power of 10
1 second = 3 power of 10, millisecond = 6 power of 10

How many milliseconds is a second? How many microseconds is a second? What are the letters for milliseconds and microseconds?

A physics problem, about the generator. Actually not difficult
There is a generator with an internal resistance of 1 ohm to supply electricity to a school. The turn ratio of step-up transformer is 1:4, the turn ratio of step-down transformer is 4:1, and the total resistance of transmission line R is 4 Ω. There are 22 classes in the school, and each class has 6 "220 V, 40 W" lights. To ensure the normal lighting of all lights, the following requirements should be met:
(1) What is the output power of the generator?
(2) How big is the electric power of the generator?
(3) What is the transmission efficiency?
(4) If only half of the total number of electricity is used and the light is normally emitted, will the output power of the generator be reduced by half?

There are 22 classes in the school, each class has 6 "220 V, 40 W" lights: 40 * 6 * 22 = 5280 W, 5280 / 220 = 24 A (1) what is the output power of the generator? Transmission line current 24 / 4 = 6a, loss 6 * 6 * 4 = 144 W, output power of the generator 5280 + 144 = 5424 w (2

What is the difference between the brightness of the hand generator bulb and that of the flashlight bulb?

The hand generator is AC, and the voltage is unstable. Because the coil cuts the magnetic line of force in different directions at different times, the voltage is unstable. Because the speed is very fast, the human eye can't see it, but it's flashing. For example, the home's white light, which uses 50 Hz AC, flashes 100 times per second, you can't see it,
The power supply for the flashlight is a branch, the voltage is very stable, so the bulb does not flash

Physics on the generator problem! Urgent!
The condition of continuous current in a circuit is that there is voltage and that there is path
In the current magnetic effect test, it is indeed a closed circuit. Where does the voltage come from?

I guess the building owner may think: in the "current magnetic effect test", there is no voltage and no current in the electrified wire
In fact, the electrified wire has voltage, because the resistance of the electrified wire is not zero, it must share part of the electromotive force of the power supply!

Conversion between kW and W

1KW=1000W

How to convert kW into kW. H

KW can become kW. H in calculation
Just take the time
But that can't be converted. One is the unit of electric work and the other is the unit of electric power

J converted to kW / h?

Notice, it's kW · h, not kW / h
KW · h is what we often call "degree". One degree of electricity is 1kW · H
1kW·h=1000W×3600s=3.6×10^6J
In fact, I also give you Baidu

How to convert kW / h into J

Notice, it's kW · h, not kW / h
KW · h is what we often call "degree". One degree of electricity is 1kW · H
1kW·h=1000W×3600s=3.6×10^6J
