Charge, Conductors, and Insulators: Introduction to Electrostatics
Electric Charge (q)
- A basic Property: Objects can have a positive or negative electric charge.
- Types: Positive charge: More protons than electrons, Negative charge: more electrons than protons.
- Conservation: Charge is neither created nor destroyed, only transferred.
- Quantized: Q=n*e. Charge exists in packets of e = 1.6 × 10⁻¹⁹ C .
Conductors
- Definition: Materials where electric charges (electrons or ions) can move freely.
- Examples: Metals like copper and silver. Salt-Solutions.
Insulators
- Definition: Materials where charges can’t move freely.
- Examples: Glass, rubber, and plastic.
Coulomb's Law in Vector Form
