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 carry energy from the cell and pass it to the components in the circuit
  • Electrons return to the positive end of the cell with less energy
• Conventional current


  The current is drawn as flowing from the positive end of the cell to the negative end, even though we now know this is incorrect
• 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
• Current is never used up in a circuit
