Compare the energy storage in a capacitor and an inductor.
Capacitor: Stores energy in an electric field. | Inductor: Stores energy in a magnetic field.
What are the differences between angular frequency (ω) and frequency (f)?
Angular Frequency (ω): Measured in rad/s, represents the rate of change of the phase. | Frequency (f): Measured in Hz, represents the number of cycles per second. Relationship: ω=2πf.
Compare the role of the inductor and capacitor in an LC circuit.
Inductor: Opposes changes in current, acting as the restoring force. | Capacitor: Resists changes in voltage, providing the inertia.
Compare the energy equations for a capacitor and inductor at their maximum energy storage.
Compare the effect of increasing L versus increasing C on the angular frequency of an LC circuit.
Increasing L: Decreases the angular frequency (ω). | Increasing C: Decreases the angular frequency (ω).
Define Inductance.
The property of a circuit element that opposes changes in current, storing energy in a magnetic field.
Define Capacitance.
The ability of a component to store energy in an electric field.
What is Angular Frequency?
The rate of change of the phase of a sinusoidal waveform, measured in radians per second.
Define Simple Harmonic Motion (SHM).
A type of periodic motion where the restoring force is directly proportional to the displacement, resulting in sinusoidal oscillations.
Define qmax in the context of LC circuits.
The maximum charge stored on the capacitor during the oscillation cycle.
What happens when the capacitor in an LC circuit is fully charged?
All energy is stored as electric potential energy in the capacitor (UC=21CVmax2), and the current is zero.
What happens when the inductor in an LC circuit is fully energized?
All energy is stored in the inductor's magnetic field (UL=21LImax2), and the voltage across the capacitor is zero.
What is the effect of increasing inductance (L) on the period of oscillation (T) in an LC circuit?
Increasing inductance increases the period of oscillation (T).
What is the effect of increasing capacitance (C) on the period of oscillation (T) in an LC circuit?
Increasing capacitance increases the period of oscillation (T).
What happens if a resistor is added in series to an LC circuit?
The oscillations will be damped, and the energy will gradually be dissipated as heat in the resistor, causing the amplitude of the oscillations to decrease over time.
