Unformatted text preview: Electric Potential of a Uniformly Charged Wire Consider a uniformly charged wire of infinite length. Charge per unit length on wire: (here assumed positive). Electric field at radius r: E = 2k . r Electric potential at radius r: Z r 1 dr = -2k [ln r - ln r0 ] V = -2k r r0 V = 2k ln r0 r Here we have used a finite, nonzero reference radius r0 = 0, . The illustration from the textbook uses Rref for the reference radius, R for the integration variable, and Rp for the radial position of the field point. tsl95 p.1/1 ...
