What is the fundamental cause of static electricity?
What is the fundamental cause of static electricity?
- The transfer of electrons between objects. (correct)
- The generation of protons through friction.
- The conversion of kinetic energy into electrical energy.
- The equalization of charge distribution on an object.
Why do charges in static electricity remain stationary?
Why do charges in static electricity remain stationary?
- Because the charges are of equal magnitude.
- Because there is no closed circuit to facilitate flow. (correct)
- Because they are constantly being replenished.
- Because the material is a conductor.

Study Notes
- Static electricity involves the accumulation of electric charges on an object.
- These charges remain stationary until discharged.
- The process of materials rubbing together can result in the transfer of electrons.
- Electron transfer leads to the creation of positive and negative charges.
- When two materials are rubbed together, one material gains electrons, acquiring a negative charge.
- Conversely, when a material loses electrons, it becomes positively charged.
- A triboelectric scale organizes materials based on their inclination to gain or lose electrons.
