series

• Series Circuits characteristics

  • Closed circuit
  • Current only follows a single path
  • The current is the same everywhere
  • Total Resistance = R1 + R2 + ...
• Series Circuit

  • Components are connected end to end
  • All the current flows through all the components
  • Can only switch them all off at once
  • Potential difference is shared across the whole circuit
  • PD of power supply = sum of PD across each component
  • Current is the same through all parts of the circuit
  • Current at one point = current at any other point
  • Total Resistance is the sum of the resistance in each component
  • Resistance of two components is bigger than just one of them, because the charge has to push through both of them when flowing round the circuit
• in a series circuit current is the

  same
• in series circuit potential difference is distributed

  equally
