Measuring Electric Charge
An electroscope effectively measures electric charge by observing the movement of metal strips that repel each other based on the charge of an object. When a charged object is brought close, the charge flows down, causing the strips to move apart; no movement indicates a neutral object. Similarly, a van de Graaff generator demonstrates charge transfer, where electrons build up and can create visible sparks, showcasing the rapid movement of charge seeking balance.In this clip
