Inductor: Stores energy in a magnetic field, resists changes in current. Capacitor: Stores energy in an electric field, resists changes in voltage.

LR Circuit: Contains inductor and resistor, current changes exponentially. LC Circuit: Contains inductor and capacitor, energy oscillates between them sinusoidally.

Inductor: $U = \frac{1}{2}LI^2$ (magnetic field). Capacitor: $U = \frac{1}{2}CV^2$ (electric field).

Inductor: Acts like an open circuit initially. Capacitor: Acts like a short circuit initially.

Inductor: Acts like a wire (short circuit) after a long time. Capacitor: Acts like an open circuit after a long time.

The proportionality constant between magnetic flux and current, measured in Henries (H). $\Phi_B = LI$

A coil of wire that resists changes in current and stores energy in a magnetic field.

A measure of the amount of magnetic field lines passing through a given area.

The time it takes for the current in an LR circuit to reach approximately 63.2% of its maximum value. $\tau = L/R$

The rate at which energy oscillates between the capacitor and inductor in an LC circuit. $\omega = \frac{1}{\sqrt{LC}}$

The electromotive force generated in a circuit due to a changing magnetic field. $\varepsilon = -L \frac{dI}{dt}$

1. Determine the inductance (L) of the inductor. 2. Find the current (I) flowing through the inductor. 3. Use the formula: $U = \frac{1}{2}LI^2$.

1. Identify the inductance (L) and resistance (R). 2. Calculate the time constant: $\tau = \frac{L}{R}$. 3. Use the formula: $I(t) = \frac{\varepsilon}{R}(1 - e^{-t/\tau})$.

1. Identify the EMF ($\varepsilon$) and time constant ($\tau$). 2. Use the formula: $V_L(t) = \varepsilon e^{-t/\tau}$.
