What is the formula for effective resistance?

What is the formula for effective resistance? Find the answer to this question and access a vast question bank that is customized for learners.

Answer: The formula for calculating effective resistance for the resistors linked in series will be –

R1 + R2 +….Rn = R

The formula for calculating effective resistance for resistors linked in parallel will be –

1/R1 +1/ R2 +…1/Rn = 1/R

Thus, using the above formula the effective resistance can be calculated for both series and parallel connections.
