Static Electricity (OCR 2.5) explores how insulators acquire charge through the transfer of electrons during friction, and how those charges create non-contact electrostatic forces and electric fields. This topic is a perennial favourite for examiners because it tests both microscopic particle understanding (AO1) and the ability to apply concepts to real-world contexts such as sparking, earthing, and charge induction (AO2). Mastery here also underpins your understanding of current electricity, electromagnetic induction, and atomic structure across the specification.
