In a simple circuit, how many possible paths are there for electricity to flow?
one
Where does the electricity in our homes come in from? Why do we use these?
fuse box; we use them to help make electricity safer to use and protect us
A kinetoscope is the first motion picture camera and took many photos of an action in progress
How can static electricity be used to remove dust and particles that cause air pollution?
Inside the factory chimney, the dust and pollution pass through a metal grid with a negative charge, giving the particles a negative charge. Then the particles pass between two metal plates with a positive charge. The particles are attracted to these plates and stick to them, and cleaner air leaves the chimney.
When electric current flows through wires, a ____ ____ is produced. This happens because _____-charged ______ are moving in the wire. We can make this force stronger by winding the wire into a ____ around an object made of _____.
magnetic field; negatively; electrons; coil; iron
