Question on: JAMB Physics - 2018
The energy needed to move a unit positive charge around a complete electric circuit is called the
A
electromotive force
B
electric potential difference
C
electric energy
D
kinetic energy
Ask EduPadi AI for a detailed answer
Correct Option: A
Electric potential difference is the work needed per unit of charge to move a test charge between the two points.
Electric energy is the energy derived from electric potential energy.
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
