Electric circuits Flashcards
1
Q
What is meant by potential difference?
A
Potential difference is the difference in the amount of energy for every coulomb of charge between 2 points in a circuit.
2
Q
What is meant by resistance?
A
Resistance is the opposition to the flow of current.
3
Q
directly proportional
What is Ohm’s law?
A
As long as the temperature is constant, current is directly proportional to potential difference.
4
