Class 10 Physics Electricity Resistors in parallel

Resistors in parallel

When two or more resistors are connected in parallel:

  • The current through the circuit is the sum of currents through each branch of the circuit.
  • The potential difference across the two points of the circuit remains the same.
  • The reciprocal of equivalent resistance of the circuit is the sum of reciprocal of the individual resistances.

 

Advantages of parallel arrangement of resistors

  • Parallel arrangement divides current in different branches and hence each component receives the required amount of current.
  • If one of the components fails in the parallel circuit, the rest work as usual.
