SAT Subject Test in Physics › Electric Potential Energy

Questions 1 - 1

On which of the following does the amount of work required to move a charge in an electric field depend?

Only the change in potential

Only the path traveled

Both the potential and the path traveled

Neither the potential nor the path traveled

Only the magnetic field

Work done by electric field is defined:

$W=-\Delta PE$

Notice that the only variable in the equation is the potential, so this is the only quantity on which work depends.
