Unformatted text preview: T 10. A constant current of i = 5A is used to charge a parallel plate capacitor with circular plates of radius R = 1cm. What is the magnitude of the magnetic field at a radius of r = 0.5 cm, which is less than R, in the region between the plates? (1) 1 x 10- 4 T (2) 5 x 10- 5 T (3) 2 x 10- 4 T (4) 6.3 x 10- 6 T (5) 0 T 11. A transformer is designed to provide a 5V output EMF when the input is 120V with a 60 Hz frequency. If there are 144 primary windings around the transformer core, how many secondary windings are necessary to provide t...
