Unit 1: Electrostatics

• Coulomb's Law: Know the formula and its vector form.

• Electric Field and Potential: Understand the definitions, units (N/C or V/m for electric field, and V for potential), and relationships.

• Capacitance: Recall the formula for a parallel plate capacitor ($C={ϵ}_{0}A/d$) and the factors it depends on.

• Dielectric Materials: What happens when a dielectric is introduced? The field decreases, and capacitance increases.

Unit 2: Current Electricity

• Ohm's Law: V = IR.

• Kirchhoff's Laws: Remember the statement of the junction rule (conservation of charge) and the loop rule (conservation of energy).

• Joule's Heating: H = I²Rt.

• Resistance: Know the factors affecting resistance and the unit, ohm (Ω).

• Meter Bridge & Potentiometer: Understand their principles and uses.

Unit 3: Magnetism and Magnetic Effects of Electric Current

• Biot-Savart Law: Its formula and applications.

• Ampere's Circuital Law: Know its statement and application to solenoids and toroids.

• Lorentz Force: $F=q(E+vB)$.

• Magnetic Dipole Moment: Formula for a current loop, $M=NIA$.

Unit 4: Electromagnetic Induction and Alternating Current

• Faraday's Law of EMI: Understand the concept of induced EMF.

• Lenz's Law: "The induced current opposes the cause producing it."

• Self-Inductance & Mutual Inductance: Know their units, Henry (H).

• AC Circuits: Be familiar with impedance, reactance, and the concept of resonance in LCR circuits.

Unit 5: Electromagnetic Waves and Wave Optics

• Maxwell's Equations: A conceptual understanding of the displacement current.

• Properties of EM waves: They are transverse, don't require a medium, and travel at the speed of light ($c=1/\sqrt{{\mu }_0{ϵ}_0}$).

• Huygen's Principle: It's the basis for explaining reflection and refraction.

• Interference & Diffraction: Know the conditions for sustained interference.

Units 6-11: Atomic Physics, Dual Nature, and more

• Photoelectric Effect: Einstein's equation, $E_{photon}=\varphi +K_{max}$.

• De Broglie Wavelength: $\lambda =h/p$.

• Bohr's Model: Know the formulas for radius and energy of an electron.

• Nuclear Physics: Radioactive decay laws, half-life, and binding energy.

• Semiconductors: Understand n-type and p-type semiconductors, and the function of a p-n junction diode.

Strategies for Success

1. Read the Textbook Thoroughly: Every line in the Samacheer Kalvi textbook is a potential one-mark question. Pay close attention to definitions, units, formulas, and key facts.

2. Make Flashcards: Write down important formulas, units, and constants on flashcards for quick revision.

3. Solve Previous Year's Papers: This is the most effective way to understand the question pattern. You'll often find repeated questions.

4. Practice Quick Calculations: Many one-mark questions involve simple numerical problems. Practice these to build speed and accuracy.

5. Focus on Key Terms: Bolded terms and definitions in the textbook are high-priority.

By following these strategies and focusing on the crucial topics, you'll be well-prepared to tackle the one-mark questions and boost your overall score in the 12th Physics Samacheer Kalvi board exam. Good luck! 🍀
