  • 1. Two metallic plates separated by a dielectric material (Ɛ=2) are connected across a 12 V battery. The two plates are

    the adjusted to accommodate a plastic material of the same thickness. If the charge on each plate is reduced to one-

    third, what is the dielectric constant of the plastic material?

    1

  • 2. The flux density emanating from a pole of generator is 20,000 gauss. A conductor one meter long cuts the flux

    perpendicularly at a speed of 40 meters per second. What voltage is developed?

    80 volts

  • 3. Two capacitors C1 = 1μF, and C2 = 3μF are connected in series. What is the equivalent capacitance? REE-Apr 2019

    0.75μF

  • 4. Calculate the AT/m to produce flux density of 0.001 Wb/m² at the center of a long straight solenoid.

    796

  • 5. A two parallel-plate capacitor charged to 15 kV has a capacitance of 4.5 x 10ˉtµF. If the plates of the capacitor of 200

    square centimeter each are separated by a distance of 1mm, what is the permittivity of the dielectric medium?

    2.54
