Important Questions Covered in Bihar Board Class 12 Physics

Q1. What is the Susceptibility of Paramagnetic Substances?

Ans: Susceptibility is constant.

Q2. What is the Unit of Surface Charge Density?

Ans: Coulomb/meter2 .

Q3. Which Substance Has the Highest Refractive Index?

Ans: Diamond.

Q4. What Is the Modulation Index in Amplitude Modulation?

Ans: The modulation index lies between 0 to 1.

Q5. How Do You Calculate the Power of an Electric Circuit?

Ans: Power of an electric circuit can be calculated with the formula as:

Power = V2/R

Q6. What Do You Mean by Lorentz Force?

Ans: Lorentz force is a magnetic force that is experienced by a charged particle when a charged particle q travels with a velocity v in a uniform magnetic field B. The Lorentz force direction is perpendicular to the direction of the magnetic field. 

Q7. Write About Shunt. Mention Its Two Uses.

Ans: Shunt is recognized as a wire of low resistance connected in parallel with the circuit. These are reasons for the use of a shunt.
