{Voltage is expressed as?} + energy/q - q/energy - I/gh - gh/q

{Is current equal to the number of electrons per second flowing through a wire?} + only in units where the charge of the electron equals one - yes - no - only in units where the charge of the electron equals the potential energy of a mouse

{In the gravitational analogy to electrostatics and electricity, what is analogous to voltage? (Here, m       is mass, h is height, and g is gravitational acceleration.} - m - mg - mgh + gh

{question?} + yes - wrong - wrong - wrong
