True or false: The work done in moving a charge through an electric field equals the change in potential. True or false: The direction of an electric field is the same as the direction of the force on a positive charge. Thanks in advance!!:D

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the components of a vector are the parts of the vectors that are to each other.
