Question 1 of 3

A battery is connected to a lamp in a simple series circuit. One wire runs from the positive terminal of the battery to the lamp. A second wire is supposed to run from the lamp back to the negative terminal, but there is a small gap in this second wire so it does not touch the negative terminal. Will the lamp light?

Question 2 of 3

A battery, a lamp, and a switch are connected in a single line (series). The wire from the battery’s positive terminal goes to the lamp, then to the switch, and the switch’s contacts are open (not touching). The wire from the switch returns to the battery’s negative terminal. Will the lamp light?

Question 3 of 3

Sam is building a tiny flashlight for his science project. He has a 2‑volt battery, a small bulb, and three pieces of wire labeled X, Y, and Z. He connects them in the following ways: 1. Wire X runs from the battery’s positive terminal to one end of the bulb. Wire Y runs from the other end of the bulb back to the battery’s negative terminal. Wire Z is not connected to anything. 2. Wire X runs from the battery’s positive terminal to the bulb. Wire Y connects the bulb’s other end to the battery’s negative terminal. Wire Z connects the positive terminal directly to the negative terminal. 3. Wire X runs from the battery’s positive terminal to the bulb. Wire Y runs from the bulb’s other end to the battery’s negative terminal. Wire Z connects the middle of wire X to the middle of wire Y. 4. Wire X runs from the battery’s positive terminal to the bulb. Wire Y runs from the bulb’s other end to a switch that is currently open. Wire Z runs from the switch back to the battery’s negative terminal. Which of these four setups will make the bulb light up?
