Class 10 Physics Electricity Resistors in series

Resistors in series

When two or more resistors are connected in series:

  • The current through the circuit remains the same.
  • The potential difference becomes sum of the individual potential difference across each resistor.
  • Equivalent resistance of the circuit is the sum of individual resistances.


Disadvantages of series arrangement of resistors

  • Two different electrical appliances, having different current requirements, cannot be connected in series as the current is constant in a series circuit.
  • If one of the components fails in a series circuit, the circuit gets broken and none of the other components get the current.
