current in series circuits

• Series circuit


  A circuit with no branches, where the current can only flow in one path around the circuit
• Electric current


  The flow of electrical charge around a circuit
• Electric current


  • Measured in amperes (A)
  • Represented by an arrow (conventional current)
• Ammeter


  • Used to measure the electric current in a circuit
• Current is never used up in a series circuit, it is the same all the way around the circuit
• Circuit components


  • Cell
  • Lamp
  • Open switch
  • Closed switch
• Scientists originally thought current flowed from positive to negative, but we now know it flows from negative to positive
