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...
