Faraday’s Law/Induction/EM Oscillation and Waves/AC Circuits - Science UIL

Faraday's Laws

describes the magnitude of the electromotive force (emf), or voltage, induced (generated) in a conductor due to electromagnetic induction (changing magnetic fields)

Lanz' Law

the direction of the induced current will oppose the change in flux that created it

Electromagnetic Waves

a form of radiation that travel though the universe

EM Spectrum

the full range of electromagnetic radiation, organized by frequency or wavelength

Radiation Pressure

the mechanical pressure that is applied on any surface due to the exchange of momentum between the electromagnetic field and the object

Polarization

a property of transverse waves which specifies the geometrical orientation of the oscillations

Wave Refraction

the bending of waves as it passes from one material to another

AC Circuits

an electrical current that regularly reverses direction and changes its value constantly with time

LC Oscillations

a circuit that is composed of the capacitor and inductor

RMS

represents the d.c. current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage

RLC Resonance

occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase

Reactance

a form of opposition generated by components in an electric circuit when alternating current (AC) passes through it

Impendence

measures movement of liquid and air up and down the oesophagus
