Question

1. voltage is a measure potential energy per unit charge. if you were a charge and moved from a higher voltage to a lower voltage how would your kinetic energy change?
2. what would the firection of the electrical force acting on you be?
3. how does your answer change is you are a negative charge?
4. what is the firection of the electric field in each case (is there any differences)?
5. how does the potential energy of a charge change as it moves along the surface fo the conductor?
6. what is the force on an electron along the surgace o0f the conductor?
7. what is the component of electric field along the surface of a conductor?
8. when the equipotential lines bend, what happeneds to the electric field lines?

Explanation / Answer

1. Kinetic energy would remain the same. Only potential energy decreases, since W = V/Q and since work is done to move a charge between potentials. 2. Positive to negative, i.e. higher potential to lower potential. 3. Negative charges go from negative to positive terminal. So the direction would be flipped. 4. Direction of E-field is always positive to negative. So higher potential to lower potential. 5. Decreases.
