Drug policy reform. Drug policy reform, also known as drug law reform, is any proposed changes to the way governments respond to the socio-cultural influence on perception of psychoactive substance use.
1 Voltage can be thought of as the driving force (although it is not really a force.) behind current. 2  Things like batteries are voltage sources. 3  The voltage across the terminals of a battery tends to stay pretty constant. 4  When you connect a device across the battery terminals a current flows through the device.
Conductors are basically a path for electricity to flow. Electricity is made up of electrons which have a negative charge. Voltage however, is the positive force that draws electrons (current) through the conductor. Therefore, conductors will always carry negative charge in the form of current and positive charges in the form of voltage.
