Exam-style question
Try this first
In a series circuit, two resistors of 4 Ω and 6 Ω are connected. Calculate the total resistance of the circuit.
Model answer
What a good answer should say
- The total resistance of the circuit is 10 Ω.
Explanation
Why this works
The correct answer is The total resistance of the circuit is 10 Ω.. This is correct because it applies the Current electricity idea named in the question, using the required quantities and units rather than mixing current, charge, potential difference, resistance, power, or energy.
The other options are less suitable because they use the wrong electrical quantity, an incompatible unit, or a rule from a different circuit context.
