Electric Circuits Flashcards
1
Q
potential difference
A
the work done per unit positive charge V =W/Q
2
Q
current
A
The rate of flow of charge I=q/t
3
Q
State Ohm’s Law
A
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature
4
Q
resistance
A
a material’s opposition to the flow of electric current
5
Q
emf
A
the total energy supplied per coulomb of charge by the cell
