Multiple choice general knowledge

Resistance of resistors R1,R2,R3,......... in series will be?

  1. 1/(R1+R2+R3+.......)

  2. R1R2R3....../R1+R2+R3+....

  3. R1+R2+R3+...........

  4. infinity

C Correct answer
Explanation

When resistors are connected in series, their individual resistances add up directly to form the total equivalent resistance. Therefore, the formula is simply R1 + R2 + R3 + ...., whereas the reciprocal sum formula applies to parallel resistors.
