5. This flow of current from positive to negative is generally known as conventional current flow.
6. Current is measured in amperes, which is abbreviated "amps".
7. When the signal has been emitted, the transducer connections in the filter junction box are changed so that the transducer can act as a receiver of sound waves.
8. The bands are separated by gaps, where electrons cannot exist.
9. There are only a few elements in the periodic table that are attracted to magnets.
10. The concept of the electric field was introduced by Michael Faraday.
