Exam-style question
Try this first
In a circuit, if the current flowing is 5 A for a time of 10 s, calculate the total charge that has flowed through the circuit.
Model answer
What a good answer should say
- The total charge that has flowed through the circuit is 50 C.
Explanation
Why this works
The correct answer is The total charge that has flowed through the circuit is 50 C.. 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.
