What is the electric potential at a given point in space, in terms of the work done to bring a small positive test charge from a reference location where the potential is taken to be zero?
a. The work done to bring the test charge to the point, divided by its charge, expressed in volts.
b. Charge per amount of work, expressed in volts.
c. The same as the electric potential energy.
d. The electric force experienced by the charge divided by charge, or newtons per coulomb.
e. The electric force experienced by the charge, calculated as charge divided by electric potential energy.
