Electric Fields:
Present everywhere but invisible.
Responsible for electric currents in solids.
Source of electric fields: electrically charged particles.
Fundamental Forces of Nature:
Gravitational
Electromagnetic
Strong Nuclear
Weak Nuclear
Static Electricity: Phenomena of stationary charges.
Two types of electric charges: Positive & Negative.
Law of Conservation of Electric Charge:
Electric charge cannot be created or destroyed.
Opposite charges attract, like charges repel.
Understanding atomic structure leads to understanding electricity.
Charged particles in atoms:
Electrons: Negatively charged.
Protons: Positively charged.
Neutrons: Neutral.
Movement of electrons creates charged ions.
Conductors: Facilitate movement of electric charge easily.
Insulators: Do not allow electric current to flow.
Semiconductors: Intermediate conductivity, significant for electronics industry.
Force F between two point charges Q1 and Q2 at a distance r:
F = k * (Q1 * Q2) / r^2
k = Coulomb's constant (8.99 x 10^9 N m²/C²).
Electric charge is quantized; elementary charge (electron) e = 1.602 x 10^-19 C.
Applies only to:
Point charges
In electrostatics (stationary charges)
Electric forces can be vectorially added.
Electric fields exert force at a distance, defined mathematically.
Surroundings of charges modify the space.
Total electric field is the vector sum of the fields produced by individual charges.
Visual representation of electric fields:
Direction of field lines indicates direction of force on a positive charge.
Field lines emanate from positive charges and terminate on negative charges.
Density of lines indicates the strength of the electric field.
Electric field influences electron movement in conductors, impacting their equilibrium state.
Electromagnetic shielding protects electronic systems from external influences.
Charged particles experience force proportional to the electric field:
F = qE
Motion can be described with kinematic equations.
Example: Electron acceleration in a parallel plate capacitor.
