The total resistance of resistors connected in series is:
- Aequal to the highest resistance present
- Bequal to the lowest resistance present
- Cgreater than the resistance of any one resistor
- Dless than the resistance of any one resistor
Correct answer: C — greater than the resistance of any one resistor. From the official ISED question bank, verified word for word.
Why
When resistors are connected in series, the electric current must flow through each component one after another, so the total opposition to that flow is the sum of all individual resistances. The full explanation — and one for every question — is in Pro.
