Flashcard: Electricity – Leaving Cert Physics Terms

Coulomb’s Law – states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. Electric Field Strength (E) – is the force per unit charge. Potential Difference (p.d.) – between two point is the… Continue Reading →
