Energy and Power in Electric Circuits (HSC SSCE Physics): Flashcards

Energy cannot be created or destroyed, only transformed

Source of potential energy for charged particles

Light and heat

Mainly light, very little heat (efficient)

Kinetic energy (movement)

Heat (thermal energy)

Rate at which energy is transformed or transferred

$P = VI$

$P = I^2R$

$P = \frac{V^2}{R}$
