Question

3. Which of the following statements correctly describes the directions of the currents I, and I,in Figure 6.2 and Figure 6.3? a. ,is counterclockwise and I, is clockwise. b. I2 is clockwise and I, is counterclockwise. c. Both I, and I, are counterclockwise. d. Both I, and I, are clockwise. 4. The following figure is an alternate view of the coil in Figure 6.4. In this end-on view the direction of the magnetic field is from right to left and the coil (in which there is an induced current) is rotating counterclockwise. The angle (0) between a line normal to the plane of the rotating coil and the direction of the magnetic field lines are shown from a different perspective than they were shown in Figure 6.4. normal to plane of the rotating coil the direction of the magnetic field is from right to left the coil is rotating counterclockwise Guided by Equation 5, indicate (by underlining) and explain your answer to the following statement The AC voltage across the load resistor (R) will be a maximum when θ is a, 900 b. 45

Answer 1

Q.no -04.

Induced voltage in conductor placing in magnetic field is given by---

E = Blvsin(thetha)

here B is magnetic field density

l is length of the conductor

v is velocty of conductor

Hence for getting maximum induced voltage the value of sin(theta) must be maximum and for this theta must be 90°.

option A is correct.
