Given that electric currents generate magnetic fields, why don't your keys get attracted to the power cords on electric appliances? c. Which energy tasks have the highest power requirements? How can you minimize the cost of operating these appliances? d. If "too many" appliances are ON simultaneously, why might a fuse blow or a circuit breaker trip? Hint: Appliances are connected in parallel. Recall what happens to the maximum current in a parallel circuit as more and more devices are added. e. Why do some appliances have 3-pronged plugs? Hint: The third prong is connected to the appliance's chassis (metal frame) and plays a role only if, due to some failure, the chassis becomes electrically charged, possibly endangering its user. f.

- Choose the correct answer. *Please answer it ASAP if you canarrow_forwardA bar magnet is dropped through a long vertical copper tube. (Assume that the magnet is smaller than the inner diameter of the tube and is not initially touching the tube). What effect will the pipe have on the magnet's fall through the tube? The magnet will fall slower as a result of its kinetic energy getting stored as magnetic energy in its magnetic field. The magnet will fall faster as a result of the increased magnetic flux, which will manifest as a corresponding increase of kinetic energy. The magnet will fall slower as a result of the magnetic repulsion of eddy currents The magnet will fall faster as a result of the magnetic attraction between the tube and the magnet, which will cause a net downward force The increased friction caused by the attraction between the magnet and the tube will slow down the fall of the magnet The tube will have no effect on the fall of the magnetarrow_forwardWhich of the answer is NOT correct for the Question: The Magnetic Core of the DC machines' inductor can be made of: a) aluminum b) stuck of laminated electrical steel c) steel in one piece d) permanent magnetarrow_forward
