How is the total resistance of resistors in parallel found?
AAdd resistances directly
BMultiply them all
CSubtract the smallest
DAdd the reciprocals
Answer & Solution
Correct answer: D. Add the reciprocals
1. For parallel resistors, add the reciprocals of the resistances.
2. Direct addition is the rule for series.
3. Multiplying or subtracting has no basis.
