The Components of Electricity

  • Voltage
  • Current
  • Resistance
  • Types of Current: AC and DC
    • Close
    • Open
    • Short


Voltage is the force pushing electrons (Current) through a wire.


Current is flow of electrons.


Resistance is the force that slows the flow of electrons.

Direct Current (DC)

Flows in only one direction negative toward positive pole of source

Alternating Current (AC)

Flows back and forth because the poles of the source alternate between positive and negative
