PHYS 250: Fund Physics: Modern Physics

Illuminate the science of flashlight power! In this video, we explore how a 6V bulb is powered by a 3V battery with an internal resistance. We calculate the power dissipation of the bulb and the terminal voltage of the battery, unraveling the physics of electrical circuits.

Explore the intricate dynamics of an L-C circuit as we analyze voltage current and energy transitions between a 60.0 millihenry inductor and a 250 microfarad capacitor. Understand the principles of energy transfer and storage in this system. Uncover key insights from calculations on capacitor charges and inductor energies at specific circuit conditions.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.
