What term describes charge produced by friction, causing sparks?

• A. Static Electricity
• B. Current Electricity
• C. Electrical Power
• D. Magnetic Charge

Answer: (A)

Static electricity is the buildup of electric charges on surfaces that occurs when materials rub against each other, transferring electrons and creating an imbalance. This charged state can linger (charges at rest) until a path for discharge appears. When the potential difference becomes large enough, the air ionizes and a rapid current flows as a spark to equalize the charges. The term specifically describes charge produced by friction, which is why it’s the best answer. The other options describe different ideas: current electricity is about ongoing flow of charges, electrical power is the rate of energy transfer, and magnetic charge isn’t a standard term in this context.
