  • Interconnection of electrical elements and provides a complete path for the current.
    Electrical circuits
  • Basic parts of a circuit:
    • Source
    • Wires
    • Load
    • Switch
  • The most basic quantity in an electric circuit
    Electric charge
  • Electric charge is measured in
    Coulombs
  • Charge can neither be created nor destroyed, only
    transferred
  • Motion of charges
    Current
  • Flow that goes from negative to positive
    Electron Flow
  • Flow that goes from positive to negative
    Conventional current flow
  • Current that remains constant with time.
    Direct Current
  • Current that varies sinusoidally with time
    Alternating Current
  • Energy required to move an electric charge through an element
    Voltage
  • Voltage is also known as
    Electromotive force
  • time rate of expending or absorbing energy
    Power
  • Power is measured in
    watts
  • Current enters the positive terminal
    Absorbing power
  • Current enters the negative terminal
    Supplying power
  • Capacity to do work
    energy
