Electric Potential Flashcards
1
Q
What is electric potential difference?
A
Electric potential difference between points A and B is the work done in moving a unit positive charge from B to A.
V = W/q ; W = work done
2
Q
What is 1v (one bolt) expressed in Coulomb?
A
1v = 1J/C (one joule per coulomb)
3
Q
What is electric field strength/intensity?
A
Electric field strength at a point in an electric field is the force experienced by a positive unit charge at that point:
E = F/q
