Editor's Notes
- #1 • Electric Potential – Energy per unit charge at a point in an electric field. • Potential Difference – The difference in electric potential between two points (voltage). • Electrical Energy – Energy used or produced by moving electric charges.
- #2 Electric potential is the energy a unit positive charge has at a specific point in an electric field. It shows how much work is needed to move the charge to that point.
- #3 This refers to electric potential energy, which is the energy a charge has because of its position within an electric field.
- #4 Voltage is the measure of electric potential difference. It tells how much energy each coulomb of charge carries. One volt means 1 joule of energy per coulomb of charge.
- #5 otential Difference (Voltage) Also called voltage, it is the difference in electric potential between two points in a circuit. It is measured in volts (V), where 1 volt = 1 joule per coulomb. This difference causes electric charges to move and produce current.
- #6 Potential difference (voltage) is what causes electric charges to move in a circuit. It provides the “push” that drives electrons, making electric current flow. It is the essential factor that allows electricity to function.
- #8 Electrical energy is the energy used or consumed by devices when electric charges move through them.
- #11 Electrical Energy Electrical energy is the energy used or consumed by an electrical device when electric charges move through it. Appliances, batteries, and chargers rely on potential difference (voltage) to make charges flow, allowing them to operate.
