Do you want to hang up all the warning signs of high-pressure dangerous fishing?

Warning signs prohibiting fishing in high-pressure dangerous areas should be hung completely.

First of all, for the safety of life, all warning signs should be hung. Because the voltage of the high-voltage warning sign is very high. According to the regulations, a striking new type of "high pressure danger, no fishing!" Installed in fish ponds under all 10 kV lines. Warning signal.

And register the hidden dangers found in fish ponds, replace and supplement the warning signs that are faded, aged, illegible, damaged or missing in time to ensure the full coverage of warning devices. So not only do you have to hang it all, but also make sure the handwriting is clean.

Introduction:

Voltage, also known as potential difference or potential difference, is a physical quantity to measure the energy difference of unit charge in electrostatic field due to different potentials. The magnitude of voltage from one point to another is equal to the work done by unit positive charge moving from one point to another due to electric field force, and the direction of voltage is defined as the direction from high potential to low potential.

The international unit system of voltage is volts (V for short), and commonly used units are millivolts (mV), microvolts (μV) and kilovolts (kV). This concept is similar to the water pressure caused by the high and low water level. It should be pointed out that the word "voltage" is generally only used for circuits, while "potential difference" and "potential difference" are generally used for all electrical phenomena.
