Question 9 • Physics

Which statement correctly describes the formation of an electric current?

Answer
A
A voltage causes electric charges to move from lower to higher potential.
B
A voltage causes electric charges to move from higher to lower potential.
C
A resistance causes electric charges to move from lower to higher potential.
D
A resistance causes electric charges to move from higher to lower potential.

Explanation

A voltage difference provides the energy that drives electric charges through a circuit. Conventional current flows from higher electric potential to lower potential, so the correct statement is that a voltage causes charges to move from higher to lower potential.
