PHYSICS 6B Ch.18 Worksheet Solutions clas.ucsb.edu/staff/vince/ 1) In a certain region of space the electric potential V is known to be constant. Is the electric field in this region (a) positive, (b) zero, or (c) negative? Electric Field is the rate of change of potential, so constant potential means E=0 2) Find the change in electric potential energy as charges of (a) 2.2 x 10 -6 C and (b) -1.1 x 10 -6 C moves from a point A to a point B, given that the change in electric potential between these points is ∆V = V B -V A = 24 V.
