Electrical Terms

2. joining of two or more pieces of material to make one piece
3. high electrical resistance to counteract the flow of energy (wood, rubber, and ceramics)
7. Refers to the number of alternating currents acting simultaneously.
8. Polarity, when there is electrode (-) and work (+); happens when the plates are positive and the electrode is negative
11. changes electricity from one voltage to another
13. the flow of energy through conductors that starts and ends at the same place
14. Pounds per square inch (PSI), controls the length of an arc across a gap
15. a force that counteracts the flow of electricity

1. the strength of an electric current in amperes; controls the size of the arc
4. wire that conducts electrical current to the metal to form the metal weld
5. Polarity, when there is electrode (+) and work (-); when the flow of electrons travel from the electrode, also known as the positive pole, to the work piece, also known as the negative pole
6. a measurement of the amount of electrical energy or power in the arc; associated with welding power or how much heat and temperature an arc produces
9. Current, The current reverses at regular intervals
10. a substance capable of readily transferring heat or electricity (copper and aluminum)
12. Current, the current flows in only one direction
16. a form of energy resulting from the presence of charged particles (protons and electrons)
