Question

Consider the AC circuit shown to the right. The current through the generator is l(t) = 2.5 sin(377 t) amps. Calculate V_gen the peak voltage across the generator. A) V_pen = 375 volts B) V_gen = 423 volts C) V_gen = 458 volts D) V_gen = 823 volts E) V_gen = 911 volts The next two problems concern the following situation Two identical conducting loops are moving in a region of uniform magnetic field (indicated by the X's). The are moving with equal speed, but loop number 1 is traveling down and loop number 2 is traveling to the right. Answer the following questions based on the position of the loops as they are shown. (Both loops are partially inside and outside of the area containing the magnetic field) 12. Compare the magnitude of the induced current in the two loops. A) I_1 I_2 13. The current in loop 1 is flowing and the current in loop 2 is flowing . A) clockwise, clockwise B) clockwise, counter-clockwise C) counter-clockwise, clockwise D) counter-clockwise, counter-clockwise E) There is not enough information given

Explanation / Answer

12. Since, both loops have the same speed and area the induced currents are equal.

13. Counter-clockwise, Clockwise (using Fleming's right hand rule)
