D) movement of electrical charges
Current is a flow of electrical charge carriers, usually electrons.The common symbol for current is the uppercase letter 'I'. The standard unit is the ampere, symbolized by 'A'

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma. Given two points in the space, called A and B, voltage is the difference of electric potentials between those two points. From the definition of electric potential it follows that: Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts).
