Recall / Warm-Up

Which of the following best distinguishes electric potential $V$ from the electric field $E$ ?

$V$ is a scalar (just a number with sign); $E$ is a vector (has direction).

$V$ is a vector and $E$ is a scalar.

$V$ and $E$ are both vectors but point in opposite directions.

$V$ and $E$ are different names for the same physical quantity.
