1. A carbon resistor is marked in colour bands in the sequence red, green, red and gold. Quote the value of the resistance.

2. Justify the statement ‘Electric field lines act from higher potential to lower potential.

3. Why does a paramagnetic sample display more magnetization when cooled?

4. What are eddy currents? How can it be minimized?

5. Give reason why moving charge in a magnetic field experiences force.

6. An electric dipole of length ‘a’ and charge ±q is placed in an electric field of intensity E with its dipole moment inclined at an angle of θ with electric field. Write the expression of its potential energy. Give the expression of potential energy and work done when it comes to the stable equilibrium position.

7. A current flowing through a copper wire is passed through another copper wire of the same length but of three times the radius of the first one. How would the drift velocity of the free electrons change? Justify your answer.

8. A wire of length L is used to form successively (i) square loop (ii) circular loop and placed in a magnetic field B. Write the expression of torque experienced by them for a given inclination. Which of the two will experience greater torque? Justify your answer.

9. A magnet is moved in the direction indicated by an arrow between the coils AB & CD as shown in the figure. Find the direction of current in each coil stating clearly the law used.
