What is equivalent resistance in parallel circuits?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
In parallel circuits, the equivalent resistance is always less than the smallest individual resistor. The formula is:
1/R_eq = 1/R₁ + 1/R₂ + 1/R₃ + ...
After calculating the sum of reciprocals, take the reciprocal of the result to find R_eq. This configuration provides multiple paths for current flow, reducing overall resistance.
