Answer:

1. Charge is a fundamental property of particles that allows them to interact with electromagnetic forces. It is measured in coulombs. Current is a rate of flow of charge. It is measured in amperes (A).

2. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

3. 'Superbolts' are real, and they flash up to 1,000 times brighter than regular lightning. ... Lightning forms when electrical charges in clouds and on the ground interact, and in most of these events the clouds are negatively charged.

4. A bolt from the blue is still cloud to ground lightning. ... It occurs when there is too much positive charge at the top of the cloud and a discharge is needed for balance. As a result of the charge being positive, the strike carries more power, can reach longer distances, and is hotter than a negative strike.
