【Electric current which is near to us. It's static electricity.】Ⅲ

In a thundercloud,elements of the cloud which are grains of ice bump against each other by a violent ascending current 上昇気流，so a friction is caused and static electricity gives off.☁

As a result,positive charge collects over the cloud and negative one collects under the cloud.☁

With a great growth of the thunderstorm,the neagtive charge collects under the cloud.The negative one is drawn up to positive one which is on the ground,so the negative is led to the ground and discharges electricity.⚡

When being struck by lightning,electric current such as no less than thousands of ampere flows,so when being out and we run into something which is struck by lightning,being inside a car is safe.☝
