If 5.0 A of battery current passes through the outside leads of a 4-wire current span spaced at 30 m (100 ft), resulting in a voltage drop of 5.0 mV with the test current applied and of 1 mV without the test current, what is a the calibration factor of the current span? 
 
A. 0.00025 A/mV 
B. 4.0 A/mV 
C. 1.25 A/mV 
D. 5.0 A/mV - ANSWER-C. 1.25 A/mV 
 
I = 5 A EC = 5 mV ENC = 1 mV 
K = I/(EC - ENC) = 5 A/(5 mV - 1 mV) = 1.25 A/mV 
 
Polarized potentials are measured 
 
A. when the rectifiers are...
