Here are some important formulas on Electromagnetic Induction and Alternating Current based on the current JEE Mains syllabus:

Electromagnetic Induction

1. Faraday's Law of Induction:

$\text{EMF (ε)} = -\frac{d\Phi}{dt} $

Here, $\Phi $is the magnetic flux through a circuit, and $\frac{d\Phi}{dt} $ is its rate of change.

2. Magnetic Flux (Φ):

$\Phi = B \cdot A \cdot \cos \theta $

Where B is the magnetic field, A is the area, and $\theta $ is the angle between the magnetic field and the normal to the surface.

3. Induced EMF in a Moving Conductor:

$\text{EMF (ε)} = B \cdot v \cdot l $

Where B is the magnetic field, v is the velocity of the conductor, and l is the length of the conductor within the field.

4. Self-Inductance (L):

L = $\frac{N \Phi}{I} $

Where N is the number of turns, $\Phi $is the magnetic flux, and I is the current.

5. Energy Stored in an Inductor:

U = $\frac{1}{2} L I^2 $

Alternating Current (AC)

1. Peak and RMS Values of AC Current:

$I_{\text{rms}} = \frac{I_0}{\sqrt{2}} $

$V_{\text{rms}} = \frac{V_0}{\sqrt{2}} $

Where $I_0 $ and $V_0 $ are peak values of current and voltage.

2. Ohm’s Law for AC Circuits:

V = I Z 

Where Z is the impedance of the circuit.

3. Impedance in Series RLC Circuit:

Z = $\sqrt{R^2 + (X_L - X_C)^2} $

Where $X_L = \omega L $ (Inductive reactance) and $X_C = \frac{1}{\omega C} $ (Capacitive reactance).

4. Resonant Frequency in RLC Circuit:

$f_0 = \frac{1}{2\pi\sqrt{LC}} $

5. Power in an AC Circuit:

$P = V_{\text{rms}} I_{\text{rms}} \cos \phi $

Where $\cos \phi $ is the power factor, with $\phi $being the phase difference between current and voltage.
