In the space below, sketch how you could light the bulb using a battery and a single piece ofbare copper wire. Explain your reasoning. If it is not possible to light the bulb with one wireand one battery, explain why not. (Note: You are not allowed to cut the wire.)2. A diagram of the light bulb used in question 1 is shown atright. Two vertical wires inside the bulb are shown, but theconnections to the base cannot be seen.Indicate on the diagram how each wire is connected inside thebase of the bulb. If several different connections are possible,state so explicitly. Briefly explain your reasoning.(continued on other side)TwoverticalwiresTutorials in Introductory Physics ©McDermott, Shaffer, & P.E.G., U.Wash.EM-UCO1110044T-P6(CK1)V3a Autumn 20043. The circuits below contain identical bulbs and batteries. Rank the five bulbs in order ofbrightness from brightest to dimmest. If two or more bulbs are equal in brightness, indicatethis in your response. Explain your reasoning.BCA
