Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
Electric current is the movement of the electrons caused by potential

without the potential difference or voltage. When there is voltage, electric
current occurs because there is a driving force for the electrons in the wire
to move.
