    We usually see the lightning in the rain.It is very bright with big noise.It is very dangerous and magical.It can broke anything,so when we see the lightning,we should turn off all the electrical and go to a safe place.When you see the lightning,you can hear a noise,because it has a high temperature,about 20,000 degrees Celsius,the air has to move fast,then you will hear the sound.A lightning lasted about 40 microseconds and current of more than 10,000 amps through.It just like short the null line and the live line.You can see the electric spark,but the proection swich will disconnect,so you'd better not play this game in your home and shouldn't fly a kite with lightning.

    We usually see lightning in the rain.It is very bright and loud.It is also very dangerous and magical.It can break anything,so when we see lightning,we should turn off all electrical appliances and go to a safe place. When you see lightning,you can also hear thunder, because lightning has a high temperature of about 20,000 degrees Celsius. The air has to move fast,causing you to hear the sound. Lightning lasts about 40 microseconds and has a current of more than 10,000 amps.It will short out null lines and live lines. You can see the electric spark, and the protection switch will disconnect,so you'd better not play computer games in your home and shouldn't fly a kite when there is lightning.
