[10] 9. Which of the following is (are) FALSE? Give your answer in the form "x, y, ..., Z" (a) In vacuum, electromagnetic waves travel at approximately 2.19 x 10-19 m/'s. (b) A transformer is a device that can be used to increase or decrease the amplitude of an alternating voltage. (c) The displacement current can be easily measured using a current measuring meter. (d) In an ideal LC circuit energy is alternatively stored in the inductor and capacitor (e) In an RLC series circuit the use of a generator can cause the oscillations not to die out. Use the following diagram for problems 10a & 10b. [10]10a. A 9.11 92 resistor, 580 mH inductor and switch are connected in series across an ideal EMF source S = 5.00 V. Switch S is closed at time t = 0. Determine the current in the Sw circuit at time t(co). Give your answer in the form "a.bc x 10"(x)" Q. [6]10b. How long after switch S is closed until the magnetic field is stable? Give your answer in the form "a bc x 10 (x) Unit". The unit must be the unit of time in the SI system
