Current in a series circuit

• 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

  • Flows from the negative end of the cell to the positive end
  • Electrons are carrying energy from the cell and pass this energy to the components in the circuit
• Conventional current

  The direction current is represented as flowing, from positive to negative, even though electrons actually flow from negative to positive
• The unit of electric current is the ampere (A)
• Ammeter


  A device used to measure the electric current in a circuit
• In a series circuit, the current is the same all the way around the circuit
