Study Notes
Johns Hopkins University Applied Physics Laboratory (APL)
- APL is a division of Johns Hopkins University dedicated to research and development in applied physics.
- As of 2023, APL employs approximately 8,000 people.
- Areas of development include national defense, space exploration, biomedical engineering, and environmental science.
- APL was originally created in 1942 to develop technology for the U.S. Navy during World War II.
LC Circuits
- An LC circuit consists of two key components: an inductor (L) and a capacitor (C).
- LC circuits are used in electronic devices to filter signals, generate oscillations, and store energy.
- The idealized assumption about energy dissipation in an LC circuit is that there is no energy loss, allowing continuous oscillation of energy between the capacitor and inductor.
- Resistance is minimized in LC circuits to reduce energy loss, ensuring efficiency and performance.
- The simplest type of inductor-capacitor network is a series or parallel LC circuit configuration.
