Answer:
1.Pint glass canning jar with lid. 3 feet insulated copper wire. 6-volt battery. Thin iron wire (unraveled picture hanging wire works great)
2.The bulb will not light because the switch is off (open). No bulbs will light in this circuit because there is no cell or battery. than one route it can take to flow from the cell and back again. ... No bulbs will light in this circuit because the electricity cannot flow around an unbroken loop back to the cell.
3.The purpose of the battery in a series circuit is to give the circuit a source of energy.
The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off.
A light bulb in a series circuit is used to determine whether or not electricity is flowing.
The purpose of the wires in a series circuit is to allow the electricity to flow from one device to the next. Wire is used to carry the flow of electrons. Metal wire is a very good conductor. Materials that do not allow electricity to flow through are called insulators or non-conductors.
4.The filament is the thin wire you see in the middle of the light bulb, held up by a glass mount. All of this exists within a glass bulb filled with an inert gas, such as argon. When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other.
5.While the answer will vary with the bulb, the cost of the energy of a light left on, especially, is fairly low no matter what bulb you're using. Energy.gov says that today's more energy-efficient bulbs typically use 25-80% less energy than traditional incandescent bulbs and that they last 3-25 times longer.
