An electric arc between two nails. An electric arc or arc discharge is an electrical breakdown of a gas that produces an ongoing plasma discharge, resulting from a current through normally nonconductive media such as air.n electric arc differs from a glow discharge in that the current density is quite high, and the voltage drop within the arc is low; at the cathode, the current density can be as high as one megaampere per square centimeter. An electric arc has a non-linear relationship between current and voltage.
According to The Bureau of Labor Statistics, the states hiring the most ultrasound techs, in relation to overall population, were as follows in 2008: 1  Florida. 2  Connecticut. 3  New Jersey. 4  Alabama. Tennessee.
This amount increases as an ultrasound technician gains experience and specialization in ultrasound sonography. There are also states which offer a relatively low salary rate.Mississippi,Arkansas, andAlabamaare just some of the states which offer not so high ultrasound tech salary. The salary in these states only range between $45,000 and $63,000 annually. Compared to the ultrasound technologists working in other states, this range may be too low. However when compared to other medical-related technician positions and non-medical jobs, this annual salary rate is still considered substantial.
