Franklin bell experiment Report Introduction After much thought as to what experiment to do‚ I decided to do an electrostatic experiment using the Franklin bell. I had to try and find different energy sources that would work for me. Any electronic instrument would give off enough electricity‚ but I eventually settled on using a electric bug zapper because it was easy to set up the crocodile clips with it. Afterwards I tried the same experiment with a television set‚ using tinfoil which gave static

Unit C2‚ C2.2.3 Covalent structures 1. This drill contains an electric motor. The diagram below shows the main parts of an electric motor. The carbon contacts are made of graphite. Springs push the contacts against the copper ring. The contacts conduct electricity to the copper ring. The copper ring rotates rapidly but does not stick or become worn because the graphite is soft and slippery. Graphite has properties which are ideal for making the contacts in an electric motor.

A paper towel which can also be known as kitchen paper is an absorbent towel made up of cellulose fibers‚ which also make up other plants like cotton and wood instead of cloth material. Although paper towels cannot be washed and used again‚ paper towels are disposable. The key to why paper towels soak up water is the cellulose fibers. Cellulose fibers are giant molecules which are made up of smaller molecules called sugar molecules (inedible) joined together. The liquid grips onto the cellulose fibers
