For resistors in series, the equivalent resistance is:
AR₁ + R₂ + ... (sum)
B1/R₁ + 1/R₂ + ...
CThe smallest of all
DProduct of all
Answer & Solution
Correct answer: A. R₁ + R₂ + ... (sum)
In series, the same current flows through all resistors. R_eq = R₁ + R₂ + ... + Rₙ. Equivalent resistance is always GREATER than any individual one.
