4. You have the following equipment: 1 non-ideal battery (with internal resistance r = 0.190 ?), plus 2 switches and plenty of wire 1 parallel-plate capacitor, initially uncharged 3 identical ohmic resistors, cach with resistance R = 4.00 ? 2 solenoid inductors. A and B, of equal length, with inductance values L, and L,. respectively Inductor A has a diameter of 10.0 cm; inductor B has a diameter of 11.0 cm. 1 laser (which can be battery-powered) that produces a single-wavelength light beam with a diameter of 1.00 mm The laser behaves as an ohmic resistor that converts 40.0% of the power it uses into light (the rest is waste heat) Two sheets of Polaroid film, plus a sheet of paper to use as a target for the laser beam. Which of Maxwell's equations explains how inductors work? a. Be specific: write the full equation and explain in words what it's saying Now consider the following experiments. Experiment : You build the circuit shown here (switch initially open), then close the switch at 0. Result: The capacitor has 75.0% of its full charge at 1 1 09 ms. Then you leave the switch closed for a total of 36.68 s, then open it and dismantle the circuit setting the capacitor aside for later. It is now charged with 148.92 mC Experiment (ii): You build the circuit shown here (with both switches initially open). The angle between the two film sheets, planes of polarization is 274°·Then you close both switches at the same moment and leave them closed for a long time. Results: The amplitude of the magnetic field in the beam that arrives at the paper is switch A switch B Polaroid 03311 mT, the energy stored in inductor B is 3.5142J and the current from the battery is 59.542 A Expenment???, Continuing from experiment (ii), you now open switch A at , :0 Result: Atr 0.250 ms, the total power being produced by the resistors in series with L, is 818.01 VW b. If you were to connect inductor A and the charged capacitor as shown here then close the switch at 0, what percentage of the total energy stored in the circuit will be in the electric field at 6.86 ms? If you were to use the two inductors L, and L, to build a simple transformer and you then connect it across a 120V AC power source, what voltage value(s) could you achieve across the secondary coil? c.
