Class 10th Lakhmir Singh & Manjit Kaur - Physics 1. Electricity

Answer :

In a circuit, resistors are connected end-to-end are said to be in series, if the same current

exists in all of them through a single path. When resistances are connected in series, their equivalent resistance is equal to the sum of the individual resistances.

R = R₁ + R₂ + R₃ + - - - - -

When resistances are connected in parallel, the reciprocal of their equivalent resistance is equal to the sum of the reciprocals of the individual resistances.

1/R = 1/R₁ + 1/R₂ + 1/ R₃ + - - - - -

The resultant resistance is less than either of the individual resistances.
