current

Cards (6)

  • current is the flow of electric charge through a conductor, measured in amps (A)
  • current can only flow if there is a potential difference and a path for the electrons to flow through
  • potential difference pushes the charge round, measured in volts
  • resistance opposes the flow of current, measured in ohms
  • the greater the resistence, the less flow of charge
  • charge= current x time (Q=IT)
