An electric field is described in cylindrical coordinates as:
E=p'(1/p) [V/m]
where p' is rho vector and p is rho. Find the voltage drop Vab where a is the the point (1,0,0) and b is (2,pi/2,1). In the the description of these points, the cylindrical coordinate notation (p,phi,z) is used, where dimensions are in [m] and angles are in radians. Voltage drop is path independent.
