Physics Concepts: Electricity, Magnetism, and Waves

This set of flashcards covers key vocabulary and concepts related to static and current electricity, magnetism, and wave behavior, as noted in the lecture.

Coulomb's Law

Describes the force between two electric charges as an inverse square law.

Electric Field

A region around a charged object where other charged objects experience a force.

Ohm's Law

States that current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points.

Resistance in Series Circuits

In a series circuit, the total resistance (R) is the sum of individual resistances; R_total = R1 + R2 + R3 + …

Resistance in Parallel Circuits

In parallel circuits, the total resistance (R) can be calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3 + …

Electric Power (P)

The rate at which electrical energy is consumed; calculated using P = IV (Power = Current x Voltage).

Magnetic Domains

Regions within a magnetic material where the magnetic orientations of atoms are aligned.

Induced Current

The current that is generated in a conductor when it is passed through a magnetic field.

Transverse Waves

Waves in which the motion of the medium is perpendicular to the direction of the wave's travel.

Longitudinal Waves

Waves in which the motion of the medium is parallel to the direction of the wave's travel.

Interference

The phenomenon where two waves superimpose to form a resultant wave; can be constructive or destructive.

Resonance

The increase in amplitude that occurs when an object is driven at its natural frequency.
