Karteikarten: Fundamentals of Electric Charges and Fields — 10 Karten

Electric charge — measured in?

Coulombs (C).

Electric charge — definition?

Property causing electromagnetic forces, measured in coulombs.

Coulomb’s Law — describes?

Force between two point charges.

Protons vs electrons — difference?

Protons positive, electrons negative charges.

Electric current — unit?

Ampere (A).

Conservation of charge — principle?

Charge cannot be created or destroyed.

Coulomb’s Law — describes?

Force between two point charges.

Charge quantization — fundamental unit?

Elementary charge e ≈ 1.6×10⁻¹⁹ C.

Electric conductors vs insulators — difference?

Conductors allow charge flow; insulators resist.

Electric field — definition?

Force per unit charge around a charge.
