Charge, static electricity, current and potential difference

By the end you’ll be able to

• describe positive and negative charge, explain charging by friction or electron transfer, and apply the rule that like charges repel and unlike charges attract
• explain electrostatic attraction between charged objects and neutral objects in terms of induced charge separation
• describe common electrostatic phenomena and hazards, including sparks and shocks, and explain ways to reduce risk such as earthing or using antistatic methods
