1 However, should there be need to buy the complete compressor, that would cost around $600 to $1,000. 2  Used and rebuilt compressors, on average, can cost $200 to $700. 3  This does not include the professional labor. 4  If the labor is included, this can bring the total up to $1,500 to $2,000.

The electric field strength between two parallel conducting plates separated by 4.00 cm is 7.50Ã104V/m. (a) What is the potential difference between the plates? (b) The plate with the lowest potential is taken to be at zero volts.
An electric field, also called an electrical field or an electrostatic field, surrounds any object that has charge. The electric field strength at any given distance from an object is directly proportional to the amount of charge on the object.
