The electroscope - Study guides, Study notes & Summaries

Electricity - A form of energy caused by the movement of electrons. load - The technical term for any electrically powered appliance The law of electric charges - the law that states that LIKE charges REPEL and OPPOSITE charges ATTRACT. Static electricity - the accumulation of excess electric charge on an object often by friction "static" = not moving this form of electricity does NOT move along a definite path (or circuit) and is NOT the form of electricity used to op...

The Electroscope

I am providing you handwritten notes of grade 12th physics . In this file have covered topics like electric charge and its properties , gold leaf electroscope and charging through induction all the given topics are covered sufficiently till boards examination. Due to limited space of uploading notes I am going to provide you notes about coulomb law in next pdf. THANK YOU AND KEEP SUPPORTING ME....BYE
