The arrangement at right consists of an open switch, a 0.20 F capacitor, a 15 2 resistor, and a battery with an EMF of 1.50 V (ignore internal resistance). The switch is then closed. Find the current through the resistor when the charge on the capacitor has dropped to 1/5 (or 0.20) of its initial value. 7.5 points] 4. A single bulb hangs 3.2 m above the floor. A table top is directly below the bulb and stands 0.6 m above the floor. If the shadow that the table top casts on the floor is 0.8 m wide, how wide is the table top? 7.5 points] 5. If a bulb labeled 40 W, 120 V is properly connected, how much current does it draw? 7.5 points](http://img.homeworklib.com/questions/713a6620-cc58-11ea-9665-29c79e25924d.png?x-oss-process=image/resize,w_560)
