Unformatted text preview: t=0. The resistance of the loop is 1.00 Ohm and the mass is 1.0 g. Assume the loop is moving to the right along xaxis and that x(t=0)=0. Find the velocity of the loop 0.1 seconds later. Problem 4. You are asked to build an LC circuit that oscillates at 10kHz. In addition, the maximal current must be 0.1 A and the maximal energy stored in the capacitor must be 105 J. What values of inductance and capacitance you must use? Problem 5. The windings of a large electromagnet have an inductance of 5.0 H and a resistance of 5.00 Ohm. The electromagnet is connected to the external EMF of 230 V. After electromagnet is switched on, how long does it take for the energy in the inductor to reach 50% of its final value? What is the final, steady value of the current in the inductor after fairly long time?...
