Which unit describes the amount of potential energy that each charge has in a circuit?
a. voltage
b. resistance
c. current
d. power

Explanation:

As we know that electric potential is defined as the work done to move a unit charge from one potential to other potential.

Here the unit charge is moved from lower potential to higher potential then in that case the work done to move the charge is stored in the form of potential energy

this is given as

so here we can say that the correct answer for the amount of potential energy for each charge is given as

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
