Chapter 3. Electric Potential Constant electric field The Electric Potential: V - Single Charge - Dipole - conservative? potential energy function?

For a point charge at the origin:

Ch3 Quiz 1 First name ______________________ Last name ___________________ Section number ______ There is an electric field given by where E 0 is a constant. What is the difference in the value of the electric potential due to this electric field between the origin and the point x=a, y=b?

Ch3 Quiz 2 First name ______________________ Last name ___________________ Section number ______ There is an electric field given by where  and  are constants. What is the difference in the value of the electric potential due to this electric field between the origin and the point x=a, y=b?

Ch3 Quiz 3 There is an electric field created by some source at the origin given by where c is a constant and r is the distance from the origin; points out from the origin. What is the difference in the value of the electric potential due to this electric field between the point x=a, y=b and the point at infinity? What is the potential function corresponding to this electric field if instead of being at the origin the source of the electric field is at point x=a, y=b?

In electrostatics: If we know V(x,y) we can find the components of electric field and In electrostatics, the electric field is conservative:

1)The electric potential V in a region of space is given by where A is a constant. Derive an expression for the electric field at any point in this region. 2)The electric potential V in a region of space is given by where c is a constant. The source of the field is at the origin. Derive an expression for the electric field at any point in this region.
