1. An electric potential has the following functional form
V(x,y,z) = x3yz + 3xyz2 + xy2z3
Determine the electric field
2. Discuss and compare the change in electric potential energy with the change in gravitational Potential Energy.
3.What is the Drift Velocity of a mobile charge carrier?
4. The electric Potential at point B in the parallel plate capacitor shown is less than the electric potential at point A by 940V. The separation between the points A and B is 0.1 cm, and the separation between the plates is 3.0cm. What is the work done by the field to move a proton from the positive to the negative plate of the capacitor?
5. Consider the concept of drift velocity. If charge carriers move in a conductor with a drift velocity, Vd, in a time ?t, arrive at an expression for the current in terms of the charge, the drift velocity, and the cross sectional area.
6. In a certain region of space, the electric field potential, V, is known to be a constant. The electric field in this region is zero. Explain why this is so.
7. In the definition for electric field, we divide the force generated by the test charge. This is also done in the definition of the electric potential, V. Explain why this is so.
8. What is the current density, J, and how is its role in determining whether a material is Ohmic or not?9. The electric field for a cylindrical capacitor is given by
Arrive at the expression of capacitance
10. A dielectric is an insulating material. When placed between the plates of a capacitor, it serves to increase the amount of energy that can be stored. Explain why this is so?

b. Power dissipated by each capacitor
c. Total power dissipated by the tree resistors
12. Charge on each capacitor
13. Equivalent resistor of the diagram
14. Current Branch
15. Bulbs
