LC Oscillations

LC Oscillations

Understanding LC Oscillations LC oscillations occur in a circuit where a capacitor and an inductor are connected together. This type of circuit is known as an LC circuit, and it’s a fundamental concept in the study of physics, especially when dealing with alternating current (AC) circuits. How LC Oscillations Occur Imagine you have a charged … Read more

AC Voltage Applied to a Series LCR Circuit

AC Voltage Applied to a Series LCR Circuit.

When AC voltage is applied to a series LCR circuit, the voltage source alternates, causing the current to change direction periodically. This current interacts with each component in the circuit—resistor, inductor, and capacitor —in unique ways due to their distinct properties: In a series LCR circuit connected to an AC source (let’s call it \(\displaystyle … Read more

Inductance

Types of Inductance

Inductance is the property of an electrical conductor by which a change in current flowing through it induces an electromotive force (emf) in both the conductor itself (self-inductance) and in any nearby conductors (mutual inductance). This is due to the magnetic field that is created around the conductor when an electric current flows through it. … Read more
