Flashcards

Electric potential

Electric potential is a measure of the electric potential energy per unit charge at a point in an electric field. It represents the work done to bring a positive unit charge from a reference point (usually infinity) to that point.

Electric potential difference

Electric potential difference is the difference in electric potential between two points in an electric field. It represents the work done to move a unit charge from one point to another.

What determines conductor resistance?

The resistance of a conductor is a measure of its opposition to the flow of electric current. It is influenced by factors like the material's resistivity, length, and cross-sectional area.

Series circuit resistance

In a series circuit, the total resistance is the sum of the individual resistances. Adding more resistors to a series circuit will always increase the total resistance.

Ohm's Law

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it, provided the resistance remains constant. This means double the voltage, double the current.
