IEB definitions Physics (Circuit) Flashcards
1
Q
Potential difference
A
The work done per unit positive charge
2
Q
Current
A
The rate of flow of charge
3
Q
Ohm’s law
A
The current through a conductor is directly proportional to the potential difference across the conductor at constant temperature
4
Q
Emf
A
The total energy supplied per coulomb of charge by the cell
5
Q
Coulomb’s law
A
Two point of charge exert a force on each other. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
