Resistance in Series
Find equivalent resistance when resistors are connected in series.
Rₛ = R₁ + R₂ + R₃ + …
Formula Explanation
In series the same current flows through each resistor.
Variables Explained
R₁, R₂… = individual resistances.
Solved Example
Three resistors 2 Ω, 3 Ω and 5 Ω in series. Equivalent resistance?
2 + 3 + 5 = 10 Ω.
