Study Notes
Charges of Protons and Electrons
- Protons carry a positive charge.
- Electrons carry a negative charge.
Interaction of Like Charges
- Like charges (e.g., proton-proton or electron-electron) repel each other when brought close together.
Conductivity of Substances
- Conductors are materials that allow electricity to pass through them easily, such as metals like copper and aluminum.
Charging by Induction
- The process of charging an uncharged body without contact with a charged body is known as induction.
- Induction involves rearranging the charge distribution within the uncharged body due to the presence of a charged object.
Measuring Charge
- An electroscope is an apparatus commonly used to measure the magnitude of charge on a body.
Insulating Substances
- Insulators are materials that do not allow electricity to pass through them easily, such as rubber, glass, and wood.
