q-bursts tia chớp điện Q/tia chớp điện nhanh Explanation: Lightning is generated when warm updrafts sweep positive charges upwards causing the rain or snow droplets to rub against each other. The droplets carry electric charges and generate electricity in the cloud. The negatively charged particles are left at the bottom of the cloud and so the ground is more positively charged than the bottom of the cloud. Then a quick burst of electricity travels from the cloud to the ground. Q ở đây có thể là dạng viết tắt của Quick. Cần xem thêm context để hiểu rõ và chọn phương án chính xác.
